Mint still does not work well with Wayland from what I can tell, and if you need features like HDR, you’re gonna have to stick to something that runs Wayland well.
While Bazzite seems fine, it is an atomic distro. If you were to try installing certain software natively, like another Firewall for instance, it might not work. And if you continue to layer such software, the update times can take longer.
Cachy(with KDE) seems very stable to me. You’ll pretty much find every software through the repo. If not, you’ll have to manually install flatpak yourself. Never had to do it myself though. But it shouldn’t be a hassle, I think.
It has its own proton variant and they recommend that you disable Steam preshader caching and increase maximum shader cache size when you’re using Proton-Cachy or GE.

From the perspective of being committed to not use anything Meta, I think it’s great that it exists. It’s very convenient that you can ask any third party or businesses to send any image or document through RCS instead of having to use WhatsApp, which a lot of them use by default these days. I personally ask them if they can first send it through Signal, but not a lot of them would do so and hence it becomes easier to make them use something that already exists on their phone by default.
Those serious about encryption would use Signal or Threema or other such apps anyway. But otherwise, this is great, especially now that it’s on both iOS and Android.
