I am using 1.03 seems to be the best bang for the buck. Also Enemy 1.05 is a very different miner compared to 1.03, one of the other reasons why I don't use it.
ccminer enemy 1.03 have critical bug - one of 16 algo is not working at all. If you dont like zealot versions - try to use ccminer enemy 1.04 - it is only bugfixes of 1.03
