I think they are cool in different ways, Bowser is more meatheaded and more rad but K Rool is more devious and cartoony, like an evil looney tunes character. Both overestimate themselves but I would say Bowser is better at cashing the checks he writes than K Rool is.
I do think K Rool is my choice though just off the fact his schtick (different occupations every game) is really fun and nearly his whole army is brawny battletoads looking motherfuckers while Bowser mostly employs fairly nonthreatening mooks. Maybe that is a testament to his competence as a leader, not sure.
