I would be skeptical of Lucifer's insight on this. By his own admission, he has never actually used Bazzite, and is basing his opinion on a single argument he had with one of the many dev's in another post. To quote Lucifer directly :

I don't have an accurate sense of how much you'd have to learn about bazzite, so I'll have trust you on this

Obviously switching to Linux will cause you to encounter new terms you won't be familiar with, or terms you are familiar with used in new and novel ways, devs and users will be opinionated and have arguments over these terms (and everything else an opinion can be had on frankly). And Lucifer's concerns on this front are not without merit, but he is overstating the severity in this case and painting a wildly inaccurate picture. And you don't actually need to gain a deep understanding of all these terms anyway. (Right away or at all depending on your goals)

But through all of that, what really matters at the end of the day is how useable is it, and how solid is the community surrounding it. And on that front I can say Bazzite has been hands down the easiest distro I have ever used for plug and play Linux gaming, and the community has been endlessly helpful and beginner friendly. I'd recommend it fully, and if you hop into their Discord, or read over their homepage and guides, it quickly becomes apparent how hard they work to make it beginner friendly.

There are some good alternatives, Mint for example is a very easy distro to make the switch from Windows. As is Pop_OS!. And with how easy steam has made running games, it's harder to find a bad choice in general nowadays.

To shift topics, I'd say the most important thing to a "smooth switch from Windows" is less the distro you choose, and more the Desktop Environment. (Which, for the point of this recommendation, is the catch all term for what your OS "looks like", where the "Start Menu" is, where your "tool bar to switch apps" is, etc) For a new Windows convert, I'd say find one that uses "KDE", as it is very similar to Windows. Bazzite offers this when you are downloading the installation image. But it's quite popular, so many others will anyway.

Sorry for the extended rant, hope this initial mess didn't make you less likely to try Linux! I was a Windows convert just a couple years ago and can say it was one of the best decisions I've ever made! Feel free to ask any questions, or hop over to the Bazzite Discord to get some helpful insights!
