Actually I went from Gentoo to Arch. I tried, tirelessly, to run a stable Gentoo desktop (server is much easier). However its not worth the wait in terms of compile times or just emerge pains to begin with. The Arch model is great if you want the cutting edge with stability. Gentoo seems more bleeding edge and less reliable. Defiance is my goto on the reliable side of cloud and virtual instances. Arch and Debian are very complimentary in my case.
