Okay, last weekend I tested seven pools, one miner each pool:
My humble opinions are:
http://p2pool.1js.us/ - not impressive, too many rejects, can`t see my statistics and payouts
https://www.multipool.us/ - good, you can mine forks dynamically, good payouts
https://ghash.io/ - good payouts
https://polmine.pl - not impressive, too many rejects, didn`t payed yet
http://eligius.st/ - too many rejects, didn`t payed yet
https://www.f2pool.com - not bad, pays
https://www.btcguild.com - heavy load for the miner, pays good
Plaese comment!
