I don't know which is the best, but I recently switched over to beertendr.com from vrm.poolinat0r.com (see my previous post on why) and things are working well (so far). You might want to check out the profitability calculator at https://pools.bloxstor.com/#/utilities to get an idea of what you might earn. I mined for a bit at pools.bloxstor.com but could not change the default payout setting so moved on to beertendr.com.
