I can't disagree with this, but I don't think it's always "5e sucks". With how popular D&D is, many many other-genre games are just not well known. There are some "big-tent" RPGs that handle the assumptions of a specific genre very well, and there are some laser-targeted modern RPGs that are designed just to play X and have very large amounts of rule support for that feel.It’s automatically assumed when people say “How do I do X with 5e”, that what the person really meant was “Please suggest alternative games to me even though I specifically asked you not to.”
There are some people who will, exactly as you say, put down D&D in other genres. But I think there's also legitimate responses educating people (maybe the OP and maybe those reading the thread) about alternatives out that are worth exploring for that particular genre.
We do the same even within D&D. I may mention how a d20 handles a particular problem that someone is having with D&D - that doesn't mean D& sucks, it that here's an elegant solution that might be worth checking out. Perhaps just to yoink and import into our game.
