BB, for me is not cheating. I really like the ease with which I can demo up a song and try new ideas and chords and change the key in seconds. With the thousands of styles, you're sure to find something that fits what your're writing.
You must understand the limitations of BB to work effectively with it. As Bat said... Zep would have had a hard time writing Whole Lotta Love on it. You can do stops and holds and other cool stuff but you gotta really know that program.... and even then... it's limited.
As far as it sounding "MIDI"... the majority of the styles are midi. So expect it to sound midi. There are hundreds of "real styles" with sampled tracks. They sound better. But even using the midi styles..... save the project and re-open it in Real Band ( a program that comes with the full versions of BB) and use Real Tracks. I bought it based on the demo songs and samples I heard, not on what the demo sounded like. I saw they had a 30 day MBG on the program, so I figured I'd try the full version with the RT's which is NOT in the demo version. Since then I have upgraded a few times and will likely upgrade again next year. They are constantly coming out with more styles and more sampled instruments.
When I write a song in BB, I move it to RB and use RT's in it. Listen to my music and the dobro, steel guitar, and fiddle among others are RT's rendered from the original BB midi in many cases.
Band in a Box, while it is good, and quite amazing in what it can do for you, is no substitute for writing talent. It will only do what you are able to tell it that you want, and if you get too fancy or creative, you will run up against it's limitations pretty quick. Anything under the Audiophile version does not use waves for it's samples, and that can show up in some crappy sounding notes in your tracks. More than one time I had to scrap the track and go in a different direction.
I write pretty standard country music and it works well, for the most part, in that situation.
The full versions of BB are quite pricey, but there's just about nothing else that I am aware of that does what BB does, at the level it does it, except for studio cats, and they are very pricey when you write and demo a lot of songs.

http://www.soundclick.com...&q=hi&newref=1 is a good example of what BB/RB/RT can do. It's composed in BB and moved to MC4 where I added the electric & Acoustic guitars. Everything else...bass, drums, trumpet, piano, pads, were all BB/RB tracks. To write this, I had to select the tempo, the style, and write the chord progressions.... So that is my creativity being enhanced by technology.
Just about every song I write these days has my "Upper Room Studio Band" playing on it.
