I tried Manjaro last year and I hated it.
Something about the distro would lock up my PC, it would freeze from time to time.
I disabled the standby/sleep function, but allowed my monitors to go into standby. But if I left my PC for an hour or two my screens would not wake up, different types and brands. I had so many issues with Manjaro and while speaking with a friend I told him I had moved over to Nobara but he was still on Manjaro. But then a few weeks later he mentioned he was running Nobara. Seems he also ditched it.
My first thought was he clearly was not being the best he could be, because he was not the one that brought in the jam filled donuts.
