I've used Win2K3 for like 1 hour total, so I have no strong opinion for or against it.
Win2k3 is pretty much win2k with everything turned off by default. Most things you do in both OSes are exactly the same, and if they are different then either it's not very different or it involves enabling services that are normally shut off. Nothing that anybody familar with win2k and armed with a new reference book or two can't handle.
Personally I'd always get the newer version of NT (like Linux, always get the newest stuff) unless their was a hardware driver problem (unlikely), or you needed to software that is only certified to run on win2k.
