1-How do you explain then that many people feel Mint is the more user friendly and favorite it over others like Manjaro, Slackware, and MX Linux? Why would any one choose Mint over simply Ubuntu?
2-Why would a two year kernel would not run modern hardware? I believe if you get a copy of Windows 7 it will run on any modern hardware. My understanding its the opposite, modern software does not work on older hardware like Windows 10 might not boot on a laptop from 2004. Don't people prefer to run the LTS version which is more stable than the rolling releases and LTS are two year olds usually?
3-I do not believe distros auto-install proprietary stuff. I know if you run Debian or OpenSUSE it doesn't have proprietary software and you should install it manually. In fact, there is a version of Debian called non-free if you want it pre-packaged with the proprietary software. And where are those same sources they are getting it from? I thought each distro has its own repositories? genuinely asking.
4-Here is a question, if all distros are basically linux what makes one different from the other? just pre-packaged software and pre-configured aesthetics? Isn't it much more difficult to run Arch or Gentoo over Mint?
I have the feels that this is a fools errand.
1. You claim this, but as has been referenced, only ZDNet says it, although I found one more who claim it's good if you come from a Windows background. Who are you talking to?
I would use one that has features I want and support for my hardware, although mostly "they" have been suggesting you use whatever your smarter friend uses, so they can help get you up to speed
2. Windows 7 is a more or less complete OS. The kernel is but one part of a full system. Not sure what you mean by LTS.
3. Not sure what you mean by proprietary. They all start with a kernel, add an update system (Yum or apt-get or make or...) and GUI and...and...and. They will use their own repositories. What things do you think you are adding from the repository?
4. No. Distros are Linux with tweaks and software added. Which Xterm(GUI), which upgrade system, what comes pre-installed, etc, etc.
My experience is that my work says "we are using version x.x.x of distro y.y.y" and that's what I have to contend with.
For home use, you don't appear to be willing to put in the time and effort to get up to speed, so why not just learn the command line on MacOS? MacOS _is_ Unix, since they ponied up the money.
