Scott,
As soon as you lowered the rate, you effectivly added quantization, so that is why you heard a differance. I really doubt that anyone could tell the diff if there was NO quantization at all. Most sequencers allow all our timing mistakes to blare through quite nicely, don't you think?
I can only see an advantage with step input. Real time recording almost ALWAYS sounds better UNquantized. (That is, if you can keep time !)
