Claymore is the one I use and it has proven to be stable and lately a few days ago Claymore did publish his new version 14 of miner as a beta version and I think when he will make it available as stable will be the best miner as always at least for me.
That sounds to me, as you have never compared it to other miners.
I have compared it to Phoenix miner and seen no improvement from Phoenix miner over Claymore however this was a very long time ago and I don't know the quality of other miners now, at that time Claymore was better and I stayed with it up until today I use it to mine Ethereum.
