I have to agree that the "Good" ending makes the most sense, but Tales (and JRPGs in general) have always been about valuing individual passions rather than going with the flow to benefit society, which is why the True Ending makes the player feel so much better than the Good Ending, I think.
Also, my favorite character ended up being Gaius. His straight man shenanigans to everyone else's antics was absolutely hysterical.

I was only listening to the conversation while doing something else and the sudden segue literally made me laugh out loud, a rare feat nowadays.
