You're not the only one. Switched a few months back after using Arch for years. It was one hell of a time sink to begin with but I find it to be unfathomably stable for a rolling release distro. I'll be sticking with it, at least until I get an irresistible itch to try Linux From Scratch.
Yea man, gentoo has a learning curve, but portage is just a dream. If you don't hack it and properly use the package.files the way they were intended it's amazingly customizable and portable.
