Who do u guys think are the best heads up online PLO or NLH players?

for NLH..
Phil Ivey
Tom Dwan
Phil Galfond
Viktor 'isildur1' blom
Daniel 'jungleman12' Cates
Di "urindanger" Dang

for PLO..
Phil Ivey
Patrik Antonius
Tom Dwan
Di "urindanger' Dang
Skjervoy
Illari Sahamies

I'd agree with most apart from Tom Dwan.

I know Omaha is Illari Sahamies main game is PLO but I see him lose consistently not really win. He has huge swings not sure exactly but obviously he is winning somewhere as he plays the highest limits..
