I personally start to like no imports more and more... They're the way to go for playable terrains, and most of the models in the UTM for some reason don't go well together. IMO most of those models don't look good when mixed, and look boring when massed... Well, not all ofcourse, some terrains really look a lot better, but the problem I have with the UTM is that I always resort to the same 2 or 3 trees and the same 2 or 3 miscellaneous doodads and then mass light and fog effects...
