I've always thought of the difference between geocentric and heliocentric to be an ego thing. Setting Earth as the center of the Universe works great, for everyone on Earth. It enforces the idea that Earth, and through that, Humans, are so important that the Universe is really centered on the Earth. Maybe this is the case, maybe its not. To assume that the Earth is the center because of us is pretty egocentric. Heliocentric places it in a more objective way, I guess? Changes the reference point to be consistent with the known laws/theory/whatever of gravity. It could also be a scaling thing as well. Applying the equations to planets while setting a reference point based on our sun would provide equations that are more easily adaptable to other galaxies or solar systems that also have planets rotating around the sun. Sure, we could try and create formulas that describe the motion of other galaxies in reference to the Earth, but that would fall apart if the Earth stopped existing.
