NUTS: Paf Poker is split into two different networks which is pretty unique (both are a skin on a different network), different currencies allowed, software is in many different languages, lots of action. Paf Poker has a decent tournament schedule for both networks.
BEATS: Slow support, different networks at Paf Poker can be confusing (not even really sure why they have 2?), limited funding options, not many promotions offered at Paf Poker, lack of a signup bonus.
