Seeing how reviving old PCs is a hugely important thing to use Linux for, it's really strange to me how difficult it is to find out which distros works best on old hardware!
People say many things, but it's hard to find real benchmarks. Tried Lubuntu and Zorin Core on one laptop I have here, and it was not OK. AntiX seems fast enough, but unfortunately too nerdy to give to a non-nerd.
@forteller I have been asking LLMs about this. Giving the specs or model of the PC i am trying to install into. Just tried a couple of old PCs, but has worked fairly well in both case.
