i keep my nvidia with ewbf on nicehash, amd with claymore on nicehashminer on nicehash, and cpus on miningpoolhub using multipoolminer. If nicehash starts supporting Lyra2z, then i'll switch my cpu to nicehash. currently Lyra2z (zcoin) has been 3 to 4 times more profitable than cryptonight.
Why not use miningpoolhub for all your miners? They charge .9% fee and you can exchange mined coins to coin of your choice for 0.2% additional fee.
So its 1.1% vs. 3% fee.
