I tried Apabi.. awful. Don't bother.
iBooks has margins that are just stupid for a small screen like an iPhone or iPod Touch.
Bluefire is the best one out there for ePub on iOS right now. To the OP, you'll just have to deal with the dictionary issue if you want a good reading experience.
Stanza is buggy. Sure, the interface might be OK, but the rendering engine is rather buggy.
