When I first began researching Linux, for my needs, I found the number of different Distros to be overwhelming. So I made this flow chart, with the intent to help new users find a starting point for choosing a distribution.
I'm open to critique, as to making this chart as helpful as possible.
EDIT: Chart updated based on suggestions in the comments.
The entire "New to Linux" section should probably just be "Mint" for anyone without an Nvidia graphics card.
For newbies, live USB test and installer experience are key, and Mint is still unmatched.
Out of curiosity, is the live USB / install experience that different than kubuntu? I've never tried mint.
I've used both, and been very pleased with both.
Mint stood out, last time I installed it, because every decision was easy and factual and about me (what time zone, what keyboard).
I essentially just pressed "next" a bunch of times.
Kubuntu was nearly that good last time I tried it, as well.
Between the two, I generally recommend Mint primarily because it keeps the messaging simple and consistent with the community.
Secondarily, because Mint doesn't have Snap (and I consider Snap bad, in a way that new Linux users are unlikely to appreciate until much later.)
