Not bad, it picked Debian based on my responses and its definitely my preference. The list below all works too, with the minuses as noted.

Seems like a decent tool!

Some more criteria which I think are meaningful:

• How often are you willing to upgrade or re-install your system ?
• How reliable does your system need to be ? Would it inconvenience you or even be a risk for your livelihood if it stops working tomorrow morning for a few days until you find time to fix it?
• If some software package has a breaking change, do you want to see the consequences of that change (a) invariably together with the next minor software update, or (b) only with the next mayor system upgrade of which you can chose the timing?
• How quick and experienced do you want to have security updates applied? For how long do you need security updates ? (btw this point is an important difference between Debian snd Ubuntu!)
• is security of your system and privacy of the user data a top concern for you?
• are you an open source software developer or do you have otherwise a strong need to run the latest software version - and how old would be the oldest version you want to tolerate?
• do you want to be, in an easy way, to be involved with the open source development community?

Nice!

Have you considered adding I want a community driven distro (as opposed to distros like Fedora or Suse)

I tested it and was surprised to not be offered Mint (the one I'm using and that fits me rather well) just because of the 'proprietary drivers' option. I checked that I wanted to use 'Free software as much as possible' but in doing so, in my mind at least, the whole sentence had equal importance, aka: I'll go free as much as I can provided I can make my computer work. Maybe it could be worth considering detailing a little more what the choice are?

I haven't installed Linux on my desktop yet, but I was leaving toward CachyOS and this tool suggested Arch. So pretty close to what I was thinking, I think, considering this took doesn't seem to include CachyOS as an option.

It seems our answers are lost very quickly (probably by design)?

I've lost the rather large feedback I've typed after filling up the questionnaire and I don't even know if it's been submitted or not... For context: Windows user thinking about switching to Linux for a while.

My result: https://distrochooser.de/en/d5a5066d255c/

Main feedback (I don't want to to re-type everything) : are the distro listed from most adapted to least? Just a list of all distro with +/-? There is little to no explanations on the list itself.

I'd also like to know how popular the distro are. From what I understand the more a distro is popular, the more ressources will be available (tuto, forum, help,...).

I'll probably try Linux with a mint on my "paperwork" laptop to see how it goes.
