In my view, there are only a certain number of formation mechanisms utilising only a limited number of compounds from a, universally speaking, small amount of space. As such, there should not be a great deal of difference between one comet and the next as there shouldn't be a great deal of difference between one asteroid and the next, though within the asteroids, there may be a mix of asteroids and 'dead' comets.
Of course 'great deal of difference' is relative.
