unless you're getting those for free, skip them both and get a RX 570. those can be had in the $50 range. it's a dramatically better GPU, and it can run off the shittiest 500W PSUs.
as to linux, it's hella supported in practically every regard, including overclocking and ROCm.
apologies for possibly misleading OP, although they didn't explicitly ask for it.
anyhow, old versions still work for some use cases, with some tweaks being necessary.
