Only going off the ones I've personally seen.

Calibur: Cool suit, lots of dark visions. Though if I'm honest, I think the visions wouldn't bother me too much, since I live in a world where you can see every bad end imaginable, and with my boundless optimism and living in the present, I wouldn't be a bad calibur.

Demons: I already feel like an old man (along with other fun things going on in my body), if I really let loose my inner wickedness, I could be an Olteca Demons. Though, I'd probably be more of a George, and maybe a Hiromi if the situation demands it.

It's a toss up between those two for me.
