Being new to UT mapping I would have to say that UnrealEd v3 is really unstable to use, compared to other packages. Coming from an architecture background using packages such as 3dsmax, AutoCAD, Bryce etc. it is really unstable. Has anyone ever found that if you hit undo more than say 4/5 times it crashes?! It's not just me that thinks this, and it's not the spec of my pc. We are using UnrealEd is part of out digital architecture course and everyone else agrees, buggy and unstable. Hopefully 2007 will be shipped with a nice new version that doesn't crash as often! Having said that, having got into mapping I love it! Bring on UT 2007 (and Battlefield 2)!!
