Got a long one. I've gone back and forth a few times (I've landed on a dual-boot Windows 10 and Arch setup, maining Arch) (btw) and my biggest takeaway is this:
Mainstream Linux distros, like Mint, do have admittedly very polished basic experiences. The problem is, though, is that it breaks down as soon as you introduce it to unique use-cases or hardware features.
Linux, specifically stable distros like Mint, are already ready for mainstream use for people who use it for basic stuff like email, web browsing, desktop social media like Facebook, and so on. It's also very usable for gaming, as we saw with Steam Deck, but still has issues primarily with adoption.
But if you have for example, a 2-in-1 laptop or a VR setup, things break down very quick. I had to configure my 2-in-1 manually and not everything works still, and VR is a joke if you don't have a Vive or Index, and even that's iffy. SteamVR is still extremely buggy and missing features.
Linux is, by design, configurable and open. This is both its greatest strength and weakness, because it allows users to set up their systems how they want, but only if they know how to. A truly "user-friendly" distro is simply not possible if you retain the configurability, which Valve knows, and is why SteamOS is locked down the way it is. This model is growing in popularity but it's not quite here yet.
At the end of the day, I still use it despite these shortcomings because I feel it's important. I should be able to look at the code and know what my machine is doing, and trust that it respects my rights and freedoms. This is why Linux, and maybe BSD, have to win. But for now, I still have a drive with Windows 10 because it's just simply not a full experience yet, and that's okay. For now
