For me it was a mixture of things, as I started off playing Jin first because I liked his design and play-style as he remined me so much of Ky when I first saw him. Which in turn lead to play Haku-men as the idea of being able to counter pretty much everything in the game and that fact Haku is Jin so switch over wasn't that hard. However that doesn't mean it was the best choice as I messed around with the whole cast for a bit, people such as Haz which felt like a good change but it's down to messing with the game and forming a opinion about every memeber of the cast then picking from there.
