I guess it depends on what you actually want to do with your computer?
I love Gentoo for the fact that I can set it up to be a nice secure and safe environment for my girlfriend to bank, shop and email her friends and family and it also gives me the chance to be completely geeky and recompile my kernal and mess with CFLAGS and other cool things...
I guess I don't understand why you'd want to move from Gentoo... _I_ can't see any other OS even comparing anymore.
Although, you've got me interested again, I think I'm going to install BeOS Dev Ed on my old Laptop, seems all the hardware should be compatible ->
