I think the outcomes are pretty similar, for an average user. But I find it a bit easier to search for help about other things I want to do with Debian/Ubuntu.
I say Debian/Ubuntu a bunch of times here because, while I like Debian a bit better, there's tons of help articles out there for Ubuntu, and 99% of them work perfectly on Debian.
I don't think it's still going strong. SteamOS 2.0, the Debian based one that was on the old steam machines has been discontinued and is no longer supported. SteamOS 3.0, on the deck, is Arch based and is not yet officially supported on anything other than a Steam Deck.
