Mostly they don't understand well all the possibilities outside of typical meter and tuning systems. They can do some but tend to push you to writing 4-beat meters in 12-note-equal-temperament. Rhythm and pitch both have far far far more possibilities which DAWs either ignore or at least make second-class options you have to kind of fight for or try a few limited tastes.
