If you want to play game, you'll have a much better time on Windows
This hasn't been true for me for a few years now. dxvk and vk3d fix a lot of the issues bad DirectX implementation causes. Games that are nearly unplayable on Windows (GTA IV, Saints Row II, etc.) play spectacularly on Linux. Vulkan as a whole is a much better API, and Proton removes a ton of the overhead that comes with gaming on Windows. This misconception that Windows is better for gaming is starting to quickly become realized, too, now that Valve and AMD are dumping so much into Linux. The reality is that if you're an NVIDIA user, you're going to have a horrible time. This isn't Linux's fault, either, but rather NVIDIA's for refusing to actually give a damn. If you look over at ProtonDB, the ones who can't play something tend to have an NVIDIA card.
I really do wish people would stop trying to persuade new people away from Linux, though. The desktop will never get the attention people want if they keep telling new users to not bother. Aside from server stuff, Linux is fantastic for gaming and media; two things that should be drawing in tons more users. When I see someone touting Windows as being better at something than Linux, it shows me that they don't have hardly any, if any, experience with what they're claiming. Of course, there will always be something niche that Windows makes easier to deal with, but for an overall experience, Linux will send you home much more content.
Linux can ran on a potato, provided you don't use or use a light desktop environment.
Not anymore, at least not without a dedicated legacy kernel. The main branch of Linux has been slowly phasing stuff out in order to cut down on the bloat. For example, support for a lot of old GPUs recently got cut.
Windows 11 doesn't even allow for local user accounts any more
You can get around this with Rufus, but what's the point? Windows has become such a chore to use, I don't understand why people don't toss it. It's always amusing to me when I see people claim that Windows and macOS are the most user friendly when workarounds for stuff like this have to exist. They're anti user as far as I'm concerned, or at least, anti private user. They're a'ok for an enterprise environment.
On topic: I'd much prefer to use the system's package manager for this. That, or just pull from a git and build the source myself. AppImage, Flatpak, and Snap are sloppy ways to make things user friendly. They don't integrate well with the rest of the desktop, make a mess out of your home directory, and add unneeded tedium thanks to permissions issues. Also, this is nothing new. pinEApple has existed for a while now, which offers an AppImage auto-updater.
