Kixx
I have owned a few of both Kixx & Chexx over the years. Kixx is typically $500-900.
My 2 second review:
Chexx gameplay is better because the hockey sticks hit each other. It feels more interactive when you "fight" your friends in a game.
Kixx mechanically lasts longer. Since the players don't hit each other the gear boxes don't wear out like they do on Kixx.
