The website LibreHunt (https://librehunt.org/) lets you tell it what is important to you in a distro and then suggests distros that meet all of or most of your criteria. It's certainly easy to use although it doesn't have a lot of criteria. I think it's good for suggesting distros, some of which I haven't heard of before or have heard of but haven't thought of using. Therefore, I think it's useful just for that reason - exploring new distros that you might not have considered.
