If it aint broke, don't fix it.
I have used arch on this same install since 2019, before that, 2016. (Just because I wanted to get my old system back ASAP and was comfortable with the process)
If I had to do it over, I would test out openSUSE tumbleweeb or endeavor, but if you have your system that works and you like it, there is absolutely nothing to gain by switching.
If you just want to explore or do it as a hobby, use an old SSD and test out different configs on a seperate drive (you can pick up a 128 or 240GB SSD for like $25) but the only differences are package managers and DE.
