I use XFS because I like acls and feel not confortable with ext3 + acl patch
(maybe I'm wrong). XFS works well. (there are a couple of glitches in 
reporting errors
"preserving permissions", but probably it will be the same with ext[23] 
acl).
I use "2.4.18-xfs".

There's no thing like Gentoo "default" kernel. You must
choose the kernel during installation.
The so called "gentoo" kernel is a pached and powered kernel, choosen to
offer more features than vanilla kernel, but not required in order to 
execute the
Gentoo distribution.

  Unfortunally, the preemptive kernel patch conflicts with current 
version of XFS,
and may cause data curruption. I don't know if just disabling the 
complile-time
option in the gentoo-patched kernel will allow xfs to run (I wouln't try 
it out on
a production machine :-). You will probably have to use the xfs-sources 
kernel, but
you will not have all the goodies a gentoo-patched kernel will have, but
it works well.

  The issues of the gentoo kernels are identical thoughout the linux 
community
because the kernel *is* Linux and it's identical in all linux 
distribution. Gentoo
gives you more freedom in choosing the kernel, and the filesystem.

Look at the kernel ebuild files in /usr/portage/sys-kernel/*
in some ebuilds you will see the list of patches that will be applied to 
that kernel.

What filesystem do you like more?

Does anyone use ext3 + acl ?
Does anyone depend on the goodies in gentoo-kernel (vfat symlinks, EVMS,
preemptive kernel....), in production systems ?
