Although it's overkill when I could have a reference sheet on my computer or on the wall, but I always remember that regexr has its cheat sheet on the side that I can easily get to. I use their cheat sheet more than the actual editor on their page.
It looks like regex101 has it as well, but the regexr one is straight to the point (at least for me). https://i.imgur.com/Hg9jGOa.png
regexr is open source, unlike regex101.
That doesn't make it better.

I prefer regex101 too. I think it has fewer features, but it has the right features and is so easy to approach.
I’m a big fan.
(For some reason RegExr.com is submitted to HN much more often than regex101.com. Is there a compelling advantage to RegExr that I've overlooked?)
