Using this right now. It’s been a little less stable then I’ve heard other people claim, I had about a day and half where I was consistently freezing up 5 minutes after login. After that was patched it has been fine.
The real test for me is if I can walk away from it for 3 weeks and update the system without the world exploding. That was what always broke Arch for me.
All my problems have been of my own making. Also I updated one computer after 18 months or thereabouts and it was fine although I wouldn't recommend leaving it that long on a computer you actually use!
