I'm a big fan of both Rumble and DC, but for your sake, I hope Rumble takes it. That, and his style is just such a treat to watch, and Rumble as champ (with a KO or dominating performance against DC) against a returning Jones 6 months or a year from now would be a huge fight. More interesting than a Jones/DC rematch, though I'm sure the banter there with DC holding the belt would be pretty entertaining.
I'm feeling this same way. Johnson is so much more interesting for the division because he's like the only guy Jones hadn't beaten. If Cormier wins, I feel like no one will REALLY care about the division because it won't feel like we have a genuine champ, as bad as that might sound.
That said, I like both guys a whole lot, but I hope/think Rumble takes it.
