Currently have my AMD rigs on moneroocean (using SRBminer to auto-switch between Cryptonight-based algos, and exchanging to XMR). Quite happy with that solution atm.
Interesting, I did not know MoneroOcean.
Lately Cryptonight is at the top of profitability considering it consumes less energy.
I will need to check it out myself.
I was able to get 4 msi vega 56 cards new at very good prices .
they do 1700 easy no flash no work just 18.8.1 and msi afterburner.
I have had them for under a week I will be trying to see what I can do with them.
The best vega 56 are the original blower fan type,as you can flash them with vega 64 bios and have almost same perf > 2000H/s
