This has been pretty much my evolution as well. Started with Ubuntu in 2006 and would distro hop a ton but eventually come back to Ubuntu. Then I found Solus and used it for 5 years and loved it for the most part. The past two years or so Solus has been been in a transition that seems like it will last a few more years and I find it is falling behind. Went back to distro hopping and finally tried Debian and not an upstream distro. I've been happy as a clam with Debian and flatpaks.
