Most users don't do any of the stupid cflags stuff on the funroll loops
website and most of the devs hate it when people do. they're as much of a
joke to the gentoo community as they are to everyone else.
packaging is the major advantage in my opinion. I've had maybe two
applications which weren't in portage and a lot more which weren't in apt
when I last tried it.

While I agree that there aren't huge gains to be made compiling your own
programs that last sentence is nothing short of rubbish. Versioning up
every day? only if you're running ~arch, and no one bar the devs would do that.
