Our review of the games, rakeback, software, cashier and account rules that separate these two rooms.
We do not think JackPoker vs KKPoker can be settled by one percentage or a lobby screenshot. We checked the network, traffic, rakeback, cashier, software and account rules to find the differences that affect regular play.
We would start with KKPoker. JackPoker has the higher listed trust score at 100/100 compared with 80/100. Neither room publishes a useful traffic figure, so we recommend checking the lobby during the hours you normally play. We still see a case for JackPoker if its NLHE and PLO offering better matches the way you play.
