To sound good with midi, you have to be a good composer, take time with editing staff notes, have excellent soundfont libraries (which can be pretty pricey) -- all in all, the skill level and tools required to get midi to sound excellent is pretty high. With realtracks pretty much anyone can sound good! Of course, songwriting is still the key ingredient in having good songs -- but for the masses, realtracks win out over midi (in my opinion).

If I was trying to compose for music libraries, I would have to become a midi expert, but I am not. Midi is great, but I think there is more money to made for PGM with the real tracks stuff.
