Well, as thatquietgirl said, it really depends on the individual. Part of it also depends on whether you're BP I or II, and whether your main problems are depression, mania, or a lot of both, and whether you have psychosis in the mix. Lamotrigine and carbamazepine are generics, for the record, and Abilify and Seroquel are still under patent and so there aren't any generics yet.
