There's a couple of threads around along the lines of 'who decides what you play?', 'my players are glad to be back to playing 5E', and 'how quickly did you bounce off a system?'.
For me, personally, it doesn't work like that. I think I'll enjoy any game (within reason) as long as I like the other players and the GM is OK.
I don't think the game itself matters all that much to me. I've played a bunch of different rule systems and settings, and generally speaking, the main factor which determined whether I enjoyed it or not wasn't the game itself, it was the people I was gaming with.
I dunno. Outside of maybe FATAL or something, I think I'd probably enjoy most TTRPGs as long as the GM is enthused about it and reasonably competent (they don't have to be a genius) and the other players aren't actively ruining it.
I think that, in general, the socializing and players is the primary thing. I think that's likely true for most gamers, in general and on the forums (it's just harder to talk about the players here, since you haven't met them and explaining how that twinkle David gets in his eye when he rolls D12s really enhances the game is a significant challenge as a writer, so we end up doing #-of-angels-on-pinheads discussions over rules minutiae).
That said, I would rather play chess with Joe than checkers; and if we're going to play Monopoly with Katie, we are
not doling out fees collected when you land on free parking, because I want this game to
end at some point. Same is true of the game systems. The system matters, just not as much as the people one is playing with (and any number of other factors).
For many groups, it also isn't as stark as
Fatal* vs anything else. I would only play highly RP-requiring games like
Blades in the Dark with some players, and some highly numbers-tracking games like
Eclipse Phase, Hero System (with Power Pools), or even
Shadowrun with others. I say that because, like that never-ending Monopoly game, someone isn't going to have fun, and if the gaming experience is about the people and hanging out with them, them not having fun is something I want to avoid.

So, in the end, I think it is an important reminder that the players and the playing of the game is more important than the rules minutiae, particularly compared to how much of the forum discussion covers such things, that doesn't mean that the game, the rules, the overall system isn't going to matter as well -- it just receives disproportionate focus.
