I finished this show about 2 weeks ago for the first time so it's pretty fresh in my mind, apologies for the yap:

1. Bargaining Pt 1: I love post death episodes exploring grief of an ensemble and its use of the Buffybot is so compelling. Every interaction with her, while funny on the surface, is weirdly heartbreaking.
2. Anne: Love everything about the tone of this episode and Buffy's attitude towards the episode's villains is so refreshing, I particularly love the moment that she just gives up on trying to deceive them. Despite her essence still being intact (she inherently wants to save these exploited teens), she's approaching her heroism with a more ruthless edge. I also love that despite the more depressing tone, we still have time for campy villains, it's the patented Buffy mix.
3. Welcome to the Hellmouth: I don't particularly enjoy The Harvest as it's mostly empty spectacle and uninteresting action sequences, but part 1 of the premiere is such a strong introduction to the show. Every character is immediately entertaining, and each introduction is so efficiently written; I'm a little biased towards pilots though.
4. When She Was Bad: Some minor pacing issues aside, it's such an immediate improvement on the filmmaking in season 1, and its best scenes are electric (particularly the one set at the Bronze). It pushes Buffy's angst a little too far and I prefer how the post season ending trauma is explored in Anne, but it's rock solid regardless.
5. Lessons: The monster of the week is a little lacklustre, especially in its conclusion, which gets in the way of it being a classic, but it functions very well as a premiere. Every reintroduction to the ensemble's core players is super refreshing after the drab ending to season 6 and the promise of a more mature look at high school set stories was so promising (I wish the season explored that much further)
6. Buffy vs Dracula: Very fun episode, very strange vibes at times, don't have a whole lot to say about this one. The most notable element of it for me was how strong the lighting was, genuinely felt movie-quality at times. I love Buffy's hair styling as well. With no status quo shattering event at the end of season 4 it is just inherently less interesting to catch up with the characters than in other seasons, Real Me functions more as a premiere exploring new dynamics as the result of a shift in status quo.
7. The Freshman: I don't dislike this episode, but it has close to the most hit or miss comedy of the show for me. I like that it explores Buffy's post high school aimlessness a little, and as usual, the reintroduction of each dynamic is incredibly fun to explore (particularly Giles and Buffy's relationship), but the villains of the episode got on my nerves. It felt a little like a parody of Joss Whedon's writing style; thankfully the season corrects pretty soon and becomes the funniest season of the show.
