[Any] comparison...?

Sorry if this seems too complicated.

Could you give out a good comparison between RM2K3 and the newer one(s)??

I just feel like after I'm done with my first on RM2K3 that I'm ready for a "next step up" kinda thing. You know, bigger and better things.

So, I'd perfer a comparison to the newEST one, in the following if you don't mind.

programming difficulty -
(I heard rm2k3 is the easiest.)

game ability -
(rm2k3 is very similar to FFVI, so what's the newest like?)

sprite difficulty -
(rm2k3 takes forever, even at just editing...)
