I don't think problem is with what is easier or harder. It's problem with tools that give you ready solutions, that make it possible to just use cookie-cutter approach without adding anything from yourself. Actually it's not even a problem it's just a consequence. Of course not everyone has time to write everything themselves, but doing that practically ensures that what you make will have unique feeling.

On the other hand, even if you use cookie cutter approach to game mechanics you could make other stuff more unique (like story or universe).
