I’ve been using Mint as my daily driver and gaming PC for years. Very happy with it.
If you’re really on the fence, and you’re building a new system, you might just want to “distro hop” for the first week or so. It’s a little work and a bit disruptive, as you’ll be re-installing the OS every few days. But just like a car, there’s nothing like actually driving it to get a feel for how much you’ll like it.
Heh, this is exactly what I went through today. I’m a paid Proton user, but ignored Proton Pass when it came out because I was already well-entrenched with BitWarden. Decided today to give it a real look. Generally pretty pleased with what I’m seeing, though I’m not entirely committed to shifting platforms.
