      Easiest to get up and running OOTB, even for newbies. It's also the most widely supported Linux distro in existence.

      coralof Ubuntu is free of charge, more secure and comes with an office suite and user tools out of the box; something that Microsoft sells at a premium when it barely functions.

      ab1 Far worse at many trivial things, many useful application just don't support Linux at all. Seriously bloated with few options.

      Because while Win10 is buggy shit with a lot of bloatware and spyware in it with horrible UI/UX... Ubuntu is FOSS, privacy focused, without bugs and anoying things, without bloatware and spyware, and with much better UI/UX. Still it has some shortcomings but it's one of the best systems and Linux distros at all.

      JackVegas Ubuntu is only a good alternative for Windows users open to a new OOTB experience and likely power users. For users who want something easy to use and familiar, Linux Mint, Pop_OS and Elementary are better alternatives by far.

      Debian is a not so good alternative for those who cares about updates. We know that to maintain the stability, the distribution (at least his stable branch) doesn't have the latest updates firstly. This way, some users won't feel truly fulfilled by the distribution.

      No SPYWARE- Not COLLECTING personal data. And not WORKING with their fellow NSA and CIA for the world domination of the internet. Open Source will eventually prevail, and GAFAMs will fail.

      Most users think ReactOS is a great alternative to Windows 10.
      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.

      lounes-tb ReactOS is an opensource reimplementation of the NT api (ms windows) with a lot of inovative ideas like the package manager and the BTRFS support.

      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.
