I liked the 4th case the most in AA. It really made me want to play because I like Edgeworth. The 3rd was also great.
I really don't like the 5th case. You're supposed to feel for Lana in the end, but the whole way through I could care less about her. I hate it when she speaks. I didn't even want to get Gant in the end. I mean, who cares about Lana?
My favorite character is Edgeworth/Mitsurugi. I like his attitude and he court room animations. He is quite cold and arrogant sometimes but I like how he comes off to people. Sometimes it seems like exactly what I would've said. I also like Godot, but I relate to Edgeworth more. :D
My favorite game is AA. JFA was okay, I love Edgeworth's re-arrival. But overall AA had me more into it. T&T is also great, but once again AA left too much of an impact. Apollo is cool too, but I like the PW games more at the moment. We just have to wait for GS5 and see how good that one comes out.
