Honestly, I'm okay if anyone wins, though if someone starts steamrolling the rest of them (Like Jeff every time they play Windjammers) I will inevitably end up rooting for the new challenger over the defending champ. Was fun to see Rorie go on a streak in Nidhogg despite that possibly being his first time though.
Brad is so fucking competitive, it's crazy. I wouldn't be surprised if he pulled out a shank and slit your throat when he loses. Which makes him pretty entertaining to watch. Jeff and Vinny showdowns are always great. Drew is like a ninja, so when he wins, it's always awesome. I just like them all to be having fun. That said, probably Vinny.
