Hmm...
1) would like to be friends with most - Navani, if we were closer in age. We'd have a lot in common. We could nerd together. Or Adolin.
2) feel is most believable in terms of motivation - I want to put Wayne but he's not from stormlight... Eshonai, maybe?
3) enjoy reading about most - Navani, hands down. She's the best. And besides, the wannabe architect in me is most interested by her fabrials. (again, I want to put wayne too)
4) find most confusing/intriguing - Hoid, duh. (wayne)
5) find makes you laugh the most - Maybe Hoid. (wayne)
6) would like to punch in the face - Gavilar and Moash. Preferably multiple times each. (wayne)
7) personally relate to most - Definitely Adolin. I'm always trying to cheer up my friends and try to get them to realize how amazing they are. (wayne)
8) feel is emotionally most realistic - ...wayne? I guess Navani.
9) shamelessly crush on the hardest - I don't know, maybe Adolin? seems cliche but he's just so nice. Or Veil. Despite me most likely hating her if I ever met her in real life.
10) is most like someone you know IRL - wayne. I give up.
