What RaGR is trying to say (in his emotionally driven mannor) is there is much more going on behind the scene in an editor then one would imagine at first glance..
Having built quite a few level/map/world builders for my own personal projects I can tell you that the difference between a good level builder and a mediocre is the features/functionality.
A good example of this is comparing 3DS max to 3DCanvas. Max is feature packed, you can do anything with it, anything, where you are limited with 3D canvas to what it was designed for (and a few extra features added in by requests). 3D canvas runs faster at higher poly/object count then 3DS max and responds quicker. But I'd choose max over 3DCanvas any day just because of the abilitys it has to do things, even if I have to wait a bit for something to be done.
