I think Daniel makes for some great TV, he carries himself well, is funny and witty, and at times can play extremeley well and read players well.
His only fault is he gets carried away with gambling a little to much because he thinks he can outplay everyone. This is somewhat common with good players but can become a big trap for losing money.
I really enjoy watching Phil Laak on GSN's High Stakes Poker also, he is a great player, who reads players well and does a lot of unusual stuff to keep his opponents guessing.
I don't care for Hellmuth much, unless he is at my table
