I think you pretty much listed my top episodes too! I love the crazy surrealness in "Restless" (and of course, that moment with Giles and Spike on the swings) and the rest of them are pretty much for the same reasons as you listed.
It's weird, my friend just burned his dvds for me like a week or so ago and I've totally gotten back into it again, and now all over my f-list its mad Buffy love time. The weird thing is that it turns out that pretty much everyone on my f-list has been a Buffy fanatic at least at one point.
