I would prefer to play Pathfinder I think. Thrilling Tales is an exciting game but Pathfinder has the potential for much more extensive development of the characters long-term, the same as Star Wars. I think that is a benefit to most level-based systems against non-level based. Thrilling Tales is better for shorter stories and long one-shots as the drama is very intense and a slower development slope would harm the sense of heroics that it generates.
