Neither is dogmatic nor could they be - even Aquinas admitted that geocentrism was merely the most probable system derived at the time. Both systems merely try to put order to the stars by their motion in the skies - both do a good job of it though some think geocentrism does a better job and explains some of the problems that heliocentrism has.
I tend towards geocentrism but not from a scientific perspective as I have too little knowledge of the subject - I do so out of respect for tradition and as it accords nicely with the scriptures.
So ultimately we will not know the true system unless we are blessed to join in the beatific vision.
I will say however, that we can certainly say that the universe has a center and an end point - that must be the case as the universe cannot be infinite.
