Which miner and pool do you prefer to mine RVN?

Hi, I am pretty new to coin mining and not a hardcore miner or trader, I just want to put my old computer to the work to have a few extra bucksI am using 3 PC with: i3 9100f + 1050ti 4GB and 2miners tool to mine RVN. Hash rate is, of course, not impressive, I would like to know if there is a better miner tool or mining pool out there to take the most profit out of my old rigsPlease leave link below, thank a lot!

p/s: I am using Ubuntu; electricity cost is not problem for me
