Is there a difference?

Is there any difference between the Enhanced world editor by BD and the Advanced world editor by Cookie? Right now I am using the EWE and I like it a lot. So would there be any good reason to switch?

And also I wanted to know how to set up a trigger so that I could have trigger maps behave like melee maps so when The comp/opponent is defeated the game ends. When it becomes a nonmelee map it doesnt end.

Thanks
