I’ve heard of Manjaro, but on the occasions when I’ve brought it up in conversation, people have almost unanimously warned me off from it in fairly strong terms… not entirely sure why, but that alone makes me reluctant to use it.
Big ones are: shadiness with funding, letting their SSL certs expire 4 times, and the fact that their idea of stable isn't additional testing, but just letting the packages sit for a week.
There was also a recent kerfluffle not covered there where they shipped a broken kernel to Apple Sillicon users without contacting the Asahi devs: https://twitter.com/AsahiLinux/status/1576356115746459648
The recommendation from the repo, EndeavourOS sounds interesting, though.
The link for the post is dead, but they've let their SSL cert expire multiple times. While it happened a few years ago, I find that a hard thing to come back from.
