Back in the day I made a lot of Quake 3 and Unreal Tournament maps. The Unreal Editor was a lot buggier than Radiant but the workflow was far superior. You could bang out a floor plan quite fast with the subtractive approach. No caulk textures to deal with either (a special texture that the renderer ignored for the sides of the boxes used to create the walls that the player never sees).
