you know i came on this forum as a fanboy, knowing little about what i was debating about.
glad to know that im not on Elite hunters annoying and not knowing anything about debating list ^_^
as for this thread, its hard to debate for bastilla because:
1. Bastilla doesnt show much outside of gameplay except for fighting back revan (with 3 jedi cohorts), distracting malak, remarkable BM, and falling to the darkside.
2. Maul is the center of many comic books, and after tpm authors embelished his story just because of his 'pimping' looks and unique lightsaber.
so in my recently more educated mind, i would have to lean with maul just because there are not as much material/positive narrative on bastila's side.
