I recently put CachyOS on my Steam Deck because I wanted more control than what Steam OS was offering me. Also I prefer to install native apps most the time. ^^;;;
I also bought a second hand Surface Pro 7 and installed Cachy on that as well and now it's my primary tablet device. (Have an iPad but I don't want to be in Apple's ecosystem.) So far I've been really happy with it.
I've been daily driving Endeavour OS for the past ... 3 years? So this is not really a big switch for me. I might consider installing that if/when I decide to reinstall my primary Desktop OS ^^;;;
