Slushpool is no option for me as they do not offer FPPS or PPS. viabtc may be an option, but the high pool fee of 4% seem a little too high for me. Also online reviews are not too positive.

Anyway thank you for your suggestions!
Anybody else know any alternative that matches my criteria?
With about 6 Exa hashes per second, Slush finds +10 blocks a day, so they do more than daily payments. And the fee is 2%, most PPS pools charge 4% due to being a risky model where they have to act like a bank for you. Also it might matter to some that its not in China but in the Czech Republic.
People doing online reviews often have biased interests. You should test each pool by yourself, remember to give it several days so it averages.
