Personally, I do not like him. For the game of poker, I think that he is great. Like Phil Hellmuth, Tony G, Will Kassouf, Mike Dentale, and every other loud mouth, Hashbrown King has his moment in poker which is causing a buzz. I think what he is doing with LATB is great. I know that I'll be watching his HU matches, and I hope Doug Polk plays him before the summer.
Think about it, who wasn't rooting for Deeb when his Q8 beat Hash's AK. That was a just great! I don't really like Deeb either with some of his antics in the past, but I was rooting for him.
To answer your question, Phil Hellmuth is the biggest jerk in poker. He has been around the longest, he berates both amateurs and pros at and off the poker table, and I'm sure he will out last all the wannabe poker brats
