Who do you enjoy playing as more?

Definitely Riku. I really like his Dark exclusive moves like Dark Break, Dark Splicer, and Dark Firaga. And his Dark Barrier is way better than any of the defending moves you can give Sora. And on top of that I find his Spirit Links way more cooler than Sora's Spirit Links.

Right now, I have been enjoying Riku more than Sora.

This is a hard one for me, because on one hand I like Riku's links and dual links much better than I like Sora's and also I feel like my Riku character is much stronger than Sora.

But on the other hand I am such a Sora fanboy (if you couldn't tell ) and this is the first time you actually get to play as the real Sora in a long time. So this is a toughy for me. Its better combat versus nostalgia for me and I think nostalgia has Riku's combat beat this time.

I find myself getting more absorbed into Riku's story (and really find myself hating the "drop" thing more and more because then I have to give a shit about Sora's less immersing story, plus dropping kills it anyway), so Riku's my choice. The only part of Sora's story I like so far* is in The Grid when he has to fight Rinzler. Otherwise, Riku's story just seems to have more going for it while Sora is a background character in a main character's clothing.

*I'm currently up to my second visit to Traverse Town so maybe Sora's story will topple Riku's at some point?
