Distro list has over 100 distro's I think were safe. Be honest, How many people every used Clear linux or even heard of it until Intel decided to git rid of it. I am betting few did. Kaisen Linux billed itself as a rescue Linux, rescue from what? Most distros have the recovery modes. Most distro's are just ego driven forks, someone wants to make themself look special so they bring out a version and pump their chest. I like this KDE vs that one. I preloaded these types of tools vs that type.
I do have to admit some Distro have gotten bloated as they become more commercial, but its still linux, Remove what you dont want and add what you do.
There are some distro that might be better on VERY old Laptops with limited memory, but often its more of I can do it on a 1990s laptop vs I need to use it on an old laptop. There is Kali Linux for the hacker, ethical or otherwise, but again any Linux can load those tools. CachyOS is top on the distro list site, but see little to no mention of it anyplace else. They claim to do a lot with Security and Speed but if that was truly so then I think it would get more press..
Linux distros are like southern baptist churches. They grow and grow then someone pisses off someone in the church. They take a bunch of friends 2 miles down the road and build another church.
