Simple mining vs nicehash

[sebas1382000]

Hello, I wanted to know if someone with experience could help me a little.

I did not know whether to put this in mining or pool. But since nicehash is a pool I decided to put it here

I have a rig of 6 gpu's. I do not know if installing the simplemining linux

Or install windows and then install nicehash

That would be more profitable
