as per my reading and research there are following kinds of miners are available in market

minergate
ethOS
claymore
cgminer
nicehash

i want to build the rig but currently i have not availability of AMD cards

so, i am planning to make from nvidia.

what are the effect of ethOS on the hash rate of nvidia and amd card with compare above miner? (for mining of ether, zcash or monero)

compare to above miners, how easy to setup ethOS?

i do not expect that you have experience of all above.

But any advice or suggestion will helpfull to me.
