I never get tired of Oshino's "Something good happen to you?" line.
This is arguably the perfect version of NISIOISIN's Bakemonogatari. The original prose stories feel a bit stuffy for how short they are, not giving the Reader the chance to really get to know the characters or the world until successive stories (for example, we don't get much of Hachikuji's true personality until after "Mayoi Snail" is resolved), and specifically we don't get enough time for banter. SHAFT's anime adaptation is bound to the way the books are divided, so it has a weird false "ending" with the second "Tsubasa Cat" episode serving as the finale for the Araragi-Senjougahara story before a later web release of the last three episodes, which actually involve the "cat" of that story's title, while also serving as the finale for Bake- as a whole. I do not dislike Bake-, and indeed I cannot dislike it, as it is the foundation on which the later series is built, but later novels and their animated adaptations feel more "whole" for having the sense that their creators are more comfortable with their art in their respective media (Bake- is actually my second favorite of SHAFT's adaptations, after the Kizumonogatari movie trilogy).
Oh!Great's largest contribution in this manga adaptation is that he preserves the quasi-avant-garde visuals of the SHAFT anime in a medium that better fits them, being print manga. For me, personally, I believe any artwork should strive to make great use of its chosen medium, and indeed SHAFT's Monogatari Series does well for a visual medium, but the "problem" is there is not enough "action" in the series to allow the animators to... well, animate. The series is mostly about talking, and so Akiyuki Shinbou and his coworkers wriggle around this by using art-style changes, or closing up on weird parts of people's bodies, or over-emphasizing erotic fanservice, or using monochromatic title cards containing large chunks of the original novels' text, &c. All of these things are pretty neat, but they don't really require animation, in the sense that they don't require movement. Manga is static, so it can arguably better use SHAFT's techniques to similar effect. Oh!Great does this perfectly, with Senjougahara's crab being shown occasionally as a mass of kanji, or showing Senjougahara's stapler attack from a vantage point in the back of Araragi's mouth, &c.
On a more basic level, Oh!Great does a pretty good job drawing Senjougahara's butt. Generally speaking, I don't care too much for Senjougahara, but I would probably blame this mostly on the purple hair of her SHAFT version. VOFAN's art for the novels always gave her black hair, and everyone else has black hair except where it's supposed to be weird, like the European vampire Shinobu or the zombie Ononoki (who I don't think is even described in-text as having blue hair, but whatever). Senjougahara's hair being purple seems to clash with the overall normalcy of the main girls, as if the aesthetic choice of her hair color was simply to have her stand out as the "main girl" among main girls. Not only does Oh!Great correct this, but he also makes everyone's hair almost white anyway, through use of harsh "lighting" to create high contrast in the sheen of everyone's black hair. Which is somehow more palatable for me than giving Senjougahara purple hair, I guess. Anyway, beyond this, Oh!Great continues to build upon the groundwork laid in his previous series, Tenjho Tenge: Senjougahara is drawn to be sexier than she appears in the anime. This is reasonable, not just for the simple fact of fanservice, but because it's supposed to be a big deal that Araragi eventually starts dating her in the story while otherwise Kanbaru, Sengoku, his sisters, arguably Hachikuji, and definitely Shinobu and Hanekawa have more chemistry with Araragi in terms of personality, and all are a bit more sexually involved with the kid, at least as concerns fanservice (Senjougahara is usually too brutal in her verbal abuse that it moves too far to be merely "S"). Senjougahara is meant to be beautiful, but her anime version feels bland in comparison to the filled niches of the sporty Kanbaru and Karen, the demure Sengoku, the smart and busty Hanekawa, the "gap moe" of Tsukihi's violent side clashing with her traditional Japanese appearance, Hachikuji's fourth-wall-breaking slips of the tongue, and the monster girls. Oh!Great "corrects" this in part by at least drawing Senjougahara's legs, thighs, and butt with great care (I guess her boobs were big-ish, too, but we already have Hanekawa for that), and of course we are spending a whole volume with Senjougahara, with only Hanekawa as competition, seen very briefly at that, so it's maybe easier to see what Araragi sees. It helps that her trademark acid tongue either seems tastefully downplayed, or otherwise Araragi's straight-man overreactions are tastefully up-played to counter.
I keep forgetting that Araragi has seen Senjougahara completely nude, but then it is possible the SHAFT version obscured things a little more than Oh!Great does here. I'd write further on the subject, but I strongly believe I've written elsewhere about ecchi comedies and the lax severity of full-frontal nudity. Essentially, it is weirdly common in the genre to have the main boy see the main girls completely nude, with nothing coming of it. Indeed, Araragi and Senjougahara begin dating shortly after the events of this volume, but their relationship will remain chaste for quite some time. The purpose of nudity in ecchi comedies is more for the Reader, so we can see butts and boobs and things. This gets tricky when we try to consider the agency of the Protagonist, who must necessarily be "blue-balled" time and again so we might kinda-sorta cuckold him by seeing these naked girls ourselves, in an external dimension where we at least have some opportunity for "release" (I don't personally beat off to such manga, but the point is I can whereas Araragi himself cannot, unless he is written to have such an allowance). We can maybe raise more questions regarding "objectification of women" as relating to two-dimensional women, most of whom are intended from the ground up to be mere caricatures, following certain tropes to appeal to 3D Readers through the lens of the 2D Protagonist, how the Protagonist's agency and that of every girl is limited by the Author-Reader dyad's need to place the characters in risque situations for our laughs and/or boners. But this is all probably a subject better suited for e.g. To Love-Ru anyway.

EDIT (06/09/2024): I bought this volume when it was new-ish, pretty sure. And bought the next two volumes with one another, so necessarily quite a bit after purchasing Volume 1. Hadn't read 2 and 3 to this day. Likewise, hadn't read beyond the first half of Koyomimonogatari among the novels until only recently. I'd been planning on finishing what was officially released of the novels much sooner. I'm still sleeping on the anime Second Season and beyond (though I've seen the Kizu movies at least twice each, and they came out later...). I think I got overwhelmed by how much shit was releasing so close to each other? And then lost interest when it seemed like Kodansha weren't going to publish the Off and Monster Seasons in the West? I've already forgotten if my reasoning for jumping back in was because SHAFT are confirmed to resume the anime. I don't think my returning to the manga has much to do with Oh!Great having just started another manga a couple weeks ago; I'd been planning on re-reading this volume for a few weeks, continuing into 2 and 3 which are sitting around untouched, then collecting future volumes, but maybe Kaijin Fugeki's release was the last push I needed?
Anyway, I wrote enough in 2019 that I don't feel I need to add much else. I considered doing that thing where I note all/most nice images of ass, thighs, boobs, &c., but... honestly, it's Oh!Great; it would take forever to catalog each and every panel with something titillating.
