      It's not linux. rather, it's legacy comes from being an alternative beast of it's own! It works well with existing windows applications; keep in mind that it is still actively being developed, so things are being improved over time.

      This is effectively a clone of Windows XP, and while it runs some software, it can not run most programs. It runs poorly on real hardware.

      Papel This is meant to be an "open source windows". Despite being in alpha, it works and you can still use all your .exes and installers, so no need to worry about having to abandon all your "windows only" programs.

      This is a real alternative. While Linux is great, this thing runs it's own kernel. This may come in very handy in the near future all things considered.

      e1359024 If you want to use Linux and want a no hassle experience, Pop Os is the way to go! Best Linux experience. They care about the desktop, the are well funded and they are doing great work. But beware, if you are coming from Window you will need some adjustment.

      Qubes can literally run windows inside itself. The only downside is worse performance and awful performance for graphics. It also wont be great on a laptop battery
