i have try a little time, for ethash the speed is same with --nofee on claymore's ethminer.
but with the good tuning of intensity, raw intensity, etc... maybe we can make same hashrate without the devfee of claymore, without the option of dual mining.
so claymore win
but sgminer have another good features (failover, multi-algo, etc...) on stock

just one thing, this sgminer don't have a option --no-retry where the miningpoolhub's sgminer have. without this feature i can't switch with another miner easily and quickly.
on the doc i have see --event-on "idle" --event-quit yes but must wait 10min, too long
