I suppose people use different distro's for different reasons. Sometimes, (as is the case where I work, the main distro we use isn't by my choice, but upper management). I like the features of this one, or the way that one looks. I use this one because it has a specific desktop, I use that one because it supports pipewire. We all have different reasons why we like or dislike certain distros. But here is something I think is often over-looked and very under-rated when choosing a distro.
Documentation
You might think that all Linux distro have good documentation, I can assure you this is not the case. Here is an experiment for you to try. Look up some things about your distro. Even some things you may already know the answer to. Does my distro work on ARM cpus? Does it support secure boot? Does it use systemd by default? Is it an LTS distro or a rolling release distro? These are just examples, there are plenty more questions you could use here.
There are actually two tests here. In the first test, don't go to your distro's website (i.e. ubuntu, fedora, debian, rocky, ... etc)
Just use something like google or duckduckgo, or whatever your search engine is... and type in one of the questions above. (i.e. "does Ubuntu support secure boot"). I think this is a good test, because many times people don't know where to go, so they just use a search engine. See where the answer links take you. Do they take you a documentation/wiki site? Or does it takes you to user forums? (i.e. reddit, openStack, linuxQuestions,org etc... I would even include user forums like fedoraforum.org. That isn't a documentation site, it's user forum site.
The second test is, go ahead and go to your "offical distro site". (If there is one) and again try to find the answers to the sample questions above.
Does this take you to a userforum? Even an external/generic forum like reddit? Or does it take you to official static documentaion pages, or better yet, a searchable wiki.
Don't get me wrong, sometimes user forums are great. Linux.org would qualify as a user forum, and I spend a little time here almost every day. I've learned a lot from this site. It's nice to have real people to talk to sometimes about real problems. Some problem are so unique, there probably isn't documentation or wiki page to cover every single question you might have.
However the down-side to unofficial user forums, is that sometimes you get bad advice/bad info. Not usually intentionally, but what works for my distro may not work for your distro. Another thing, is that sometimes (stackoverflow is pretty bad about this) most of the info is about 3 or 4 years out of date. Linux.org is pretty good about staying current. The other bad thing about user forums, is that I have an emergency right now, but no one who seems to know the answer is on-line right now. Static doc/wiki pages are always there, even when everyone else is asleep.
From worst to best, this is what I have encountered.
1. They have a download page, and not much else.
2. They have a download page, and a facebook link that hasn't been updated in a year or two.
3. There is no distro specific documentation at all. Whatever there is, is in places in stackoverlow and reddit.
4. They do at least have a distro specific user forum, and some of the people are knowledgeable.
5. They have "some" documenation. This is a hard one to grade. But I would ask, do they have more than 30 pages of documentation?
6. They have a lot of documentation, but you can't see most of it unless you pay for support or have a subscription ( think Redhat here ).
7. They have hundreds of pages of documentation, but it's hard to search, you have to go back out to google to find the page you're looking for.
8. They have thousands of pages of documentaion, and it's in a searchable wiki. (fedora is a good example).
If you're an experienced user, and you've been using Linux for years, this probably doesn't matter that much to you. You either know the answers, or know where to get them. But if you're a noob. Someone who is just getting started with less than a year or two of experience. Documentation is really a must have. If I was advising someone which distro to start with... I would say a well documented one is a big plus.
