Pretty much every editor is capable of doing Wow-like maps with as much or more quality, it just takes extremely talented people to get it right (and that's what happens).
Same way, pretty much every architect (well, the majority), uses autoCAD as a standard tool. But there are good and bad architects, so some projects are awesome and others aren't.
Generalizing the wow phenomena to their tools is wrong, very very wrong.
