"baiten kaitos:eternal wings and the lost ocean" or "skies of arcadia"?

[Stats87]

I liked Baiten Kaitos better,(never played sequel) but like Soriku pointed out, SoA is probably rarer. SoA has a more classic battle system and BK uses a Card Battle system that is pretty fun.

BK is much better technically since it was made more recently, with SoA being a port of a DC game.
