My arch broke down. I am thinking about trying a new distro, should I go for Gentoo or another arch based distro like Manjaro or antregos etc.

IMHO gentoo is fun but its just too much compiling for me, can't take that on my day to day workstation ... I would suggest you switch to ubuntu based distro if you want less hassle or stick with arch and try to figure out how to hold it stable ... anyway I switched back to win10 and use bash for windows now xD

FreeBSD ... And never look back. 😎
