Label, your favourite Angel episodes are pretty much the same as mine. I agree that Angel had just as many standout brilliant episodes as its parent series; but as the show was more arc-based, they all tend to blend together more.
Are You Now Or Have You Ever Been was a phenomenal episode which I rewatched recently. The Trial in season two I enjoyed a lot too. Anything with Faith is a standout.
And, contrary to some around here, I loved Angel season 5. Interesting, because the fifth year of Buffy and Angel is probably one of my favourite seasons of both shows (but Buffy season 3 just beats its fifth season. Just)
