Lets go with "more sense" = simpler.

They both provide accurate predictions, but the heliocentric model that gravity holds the Planets in orbit around the Sun has a lower Kolmogorov complexity than a geocentric model in which the Earth is central, but everything has weird complicated paths as they orbit.

Are you comparing the Copernican system or the Keplerian system? The straight Copernican system is about as complicated as the geocentrist system. You only get the reduction in complexity when you go for full out Keplerian. And note that there were other pre-Kepler systems that were arguably simpler than the Copernican system. this article gives a good brief summary.

My mistake. I was thinking of Keplerian when I wrote this.
