For your info the best place to get info about running a WoW server is here (yes, running Emus is a hobby of mine):
http://forum.uw-crew.org/
This is where they release the lastest and greatest WoWEmu and Mangos stuff out there. WoWEmu is further along that Mangos but its all TCL scrpited and it's a bit buggy at times, but the funnest. Mangos is still in development.
You download re-packs of the vanilla UWC server which give you all the scripts both client and server side to get things going. I mess around with the AFG funserver (lots of custom content) and Neils Repack because they are the most "done". The fun thing though about the TCL scripting is that you can tweak the heck out of everything without compiling, although if more than 30-50 people log on to your system it becomes a lag/crash fest.
Xoaswow is probably based on the closed source wowow engine which is more like the traditional MySQL/Server setup that EQEmu has (Mangos will be the open source implementation like this), which is a lot more stable.
I would say that EQEmu is better done and further along.
