None of them.

You asked for the one most stable. RHEL5 currently comes with its own
version of Xen, based on well-tested Xen 3.1.2 plus lots of RH
patches. It's kernel is based on 2.6.18, but also with lots of RH
patches so it has some newer kernel features (like ext4). Redhat
actively maintain this version to have the latest security and bug fix
for the life time of RHEL5, and it works great for common uses (with
Windows/Linux domUs).

That being said, If you use some kind of domU (like Solaris or
opensolaris), you might need newer Xen version. For this purpose you
can install a packaged version of Xen 3.4.3 for RHEL from
http://www.gitco.de/repo/ that should just work.

Xen 4.0 and pv_ops kernel (based on 2.6.32) or Suse xen kernel
(2.6.34) has more features (like blktap2), but it's also not as
well-tested, so you might find some bugs here and there. Personally I
have a dev system with RHEL5/Xen-4.0/2.6.34 kernel +
http://code.google.com/p/gentoo-xen-kernel/downloads/detail?name=xen-patches-2.6.34-1.tar.bz2&can=2&q=

If you don't want to bother with dom0 OS selection, you could go down
XenServer and XCP (the dev version) path, like David suggested.
