it seems that you will not like any bitcoin poker site
you can't play on browser in SWC
and you don't like the witdrawal time in Betcoin
+
you found lucky flop poor with traffic ( it has the most traffic after SWC and Betcoin )
so I think you will not be satisfied with bitcoin poker sites ( and I agree with that ., we are all still waiting the dream site )
i think maybe OP likes nitrogensport poker or bitcasino poker, but the traffic there is less than luckyflop, 50-70 online players on luckyflop is good enough IMO, or he won't have any choice, because only 2 sites(betcoin.ag and swc) have more than 100 players, but they only have PC client
