I found this site a while back - basically it will ask you a bunch of questions on your usage of your PC, and will came out with a list of recommended distros, and a list of reasons why YOU could like or not like it.
There are some similar sites to this one, but since I’m not familiar with them, I won’t post them. They are simply DuckDuckGo-able though.
Showing all results it’s fine IMO, they just need to make obvious the results are ranked with the “best match” at the top, so if the user doesn’t know better or doesn’t have any objections, they’ll pick the top one.
