I haven't looked at in in years, but their code tends to strive for more simplicity, to ease portability. Which usually means that they can't make the same sacrifices as FreeBSD does, especially regarding SMP and multi-care systems. But I've heard that this got a lot better in recent years and by postponing that skipped a few errors that FreeBSD made. Also their package system (pkgsrc) is a bit different from FreeBSDs ports, and those tend to be highly subjective, regarding ease of use and the amount of software packages covered. My info might be a bit outdated, but I think NetBSD provides the best Xen support.
