I found myself in the same boat as you a while back. I made the switch to Funtoo and have not looked back...
The first reason i switched was because of the git based portage tree(which gentoo now has) It was faster to sync and easier to browse if the need be.
The second reason was the name. Linux should be Fun too.... :)
Other reasons are the community i felt better with the funtoo guys for some reason back then...Can't remeber specifics and part of it was the main man behind funtoo.
To me funtoo also felt like the best balance between bleeding edge and having a system that just works.
