I've read a little bit of Angel: After the Fall, which I didn't care for, the least of which was because of it clashing with series canon, the Fray crossover into Buffy's comics, because it had Mel in it (which raised the quality enough for me to finish it but was not without its moments of bad writing),.and the first chunk of Angel & Faith (eleven or twelve issues at the time, I think), which I found better than Season 8 or After the Fall, but still not up to par with Fray. Still, I think the writing benefited a lot more from good handling of the chemistry between Faith and Angel. This is a far off memory, though, so don't take it for gospel. I just remember having enjoyed it more, not much in the way of details.
