Jackpot Factory
I have no experience with Kiwi, but if its on the CM list then I'm sure its fine. I quit playing at Playtechs although I like the software. They all just take TOO long to pay out.
I play only at iNetBet (24 hrs or less payouts--rtg), Casino Extreme (instant payouts to neteller, 20% cashback if you lose--rtg), Global Player (fun vp tourneys, super faster withdrawals) and Jackpot Factory MG's--All Slots and All Jackpots.
I think there are a lot of good Microgaming casinos, but my experiences with AS & AJ have been excellent so I don't play elsewhere anymore. Plus, they will flush a withdrawal on request in a short amount of time usually, and many times my withdrawals are done in 12 hours--always in a day. All of the above mentioned casinos do cashouts everyday, whereas some don't process on weekends.
Comp points are fair with all of them, too. Best is Jackpot Factory, you don't have to wager your comp money, it's yours to cash out (if you have at least $20, that's them minimum withdrawal). I seem to win a lot of contest bonuses with JF, too, and you only have to wager bonus money 5 times, and vp is okay, unlike a lot of casinos where you have to play your bonuses more than that and slots only.
Good luck!
