Arch doesn't break on its own, but Arch is Arch, which means you might get an update where a post on the news says "btw, if you have changes to X file, your system won't boot" or something. People don't read the news before installing updates, but that's also fine because I also don't read them and have been using Arch for over a decade, and my system never broke on its own (to be entirely fair, one time back in 2007 I think, my system stopped showing jpg wallpapers because one library hadn't been updated, the fix was to update my system the next day).

Also Arch is not hard to install, it's labor intensive, but anyone with minimal Linux knowledge should be able to do it (and probably ask themselves why they're being forced to do that).

Finally, Arch is not "cool", lots of cringe people have ruined it and sometimes saying you use Arch sounds similar to saying you run Kali depending on the context.

Long story short, if you're happy with what you have keep using it, I'm fairly confident you can get hyprland and everything else working on whatever distro you're currently using. But if you're determined to use Arch you should be fine too.
