I would have to say GUEdit. Personally because SCM Toolkit has never worked for me and I'm too lazy to try to make it work. GUEdit is easier once you get Java Runtime 1.1.0.2 or something like that. I learned the hard way on creating terrain on GUEdit and changing player colors. Overall, I would have to say GUEdit because it's easier to use mostly. Good luck!
