It all comes down to what you like then, if you are a monkey you like bananas, if you a re a cat you like fish. If you like "real" you like Roland, if you like "interesting" you like KORG. At the end of the day if you are a good musician you can write a masterpiece with much less than these monsters. So many people have done it before with much less stuff (in terms of quality and variety of sounds). But the bottom line for me, and thats where my preference for Roland stands is that our ears are much more comfortable with "real" sounds than with "not-so-real". I do not mean that non real sounds are not funny or cool (i love tube distortion, but even this has some naturalness in it, actual electrons flow in the tube depending on the way you play your guitar which gives you what we call "analog" sound.) I would say the difference is like Home made food (that would be the real sound) versus tin food (that would be the not-so-real sound). It's a matter of taste.
