Leaving the performance boost issue alone (I don't want to argue about it, it
is different from system to system). Also I am not a big fan of RPM based
systems also (too much personal trauma in my early years).
I used Gentoo for about 1.5 years on my home system and always used debian in
work. So from personal experience I can say that your point about portage and
USE flags being miles ahead are not fine, yes the portage system is good, so
is dpkg. I don't remember the last time I had to wade through make files for
my debian desktop.
I guess you have nice bit of hardware if you can emerge world over night. The
main problem I had with portage was the number of times I had to go in and
edit an ebuild file to make stuff work. I have never fiddled with an deb file
ever, unless I am making my own debs.

Yes the Gentoo community are nice and help full, mostly muppet free.

Yes they do, I remember a hole thing about how Debian was losing users to
Gentoo.
