I would have to say, favorite yeast for APA would be Nottingham.
Typically though, with a very hoppy beer, I will just use whatever yeast I have laying around. The yeast is not super critical when the beer is buried in hops. I do the same for porters and stouts. I will usually have either Notty, US-05, or S-04 laying around. Also S-189, great lager yeast, and I would not be adverse to using lager yeast for an APA (or APL). This style is all about the hops. Yeast is an afterthought. Unless you want hazy... but that's another story.
