Daniel Negreanu is an important player in poker history. Today, he still remains relevant in high roller events with players who, while less marketable, are actually considered the "elites". Gus Hanson is a notable figure in poker, and he did make people aware that aggression is effective - but for all intensive purposes his relevance in the game of poker is extremely insignificant right now.
Negreanu has continued to do well for himself in the toughest games
Negreanu >>>>>>> Hanson
People need to spend less time talking about TV personalities like Gus Hanson and more time talking about poker geniuses like Scott Seiver, Phil Galfond, Selbst, etc.
