I feel like ethminer 0.11.0 gives better hashrate than claymore. Claymore single gives me 197 MH/s and dual with DCR gives 194 MH/s While ethminer 0.11.0 is giving 201
I tried them all and think the newest dev is the best. Tell me if your experience is different.
On ethminer 0.12.0.dev2 one of my rigs started dropping from full utilization and all 6 GPUs gone to 70-80 % and miner restarted 2 times then I switched to 0.11.0 But on ethminer 0.11.0 its working with no problems.
