I'm going to disagree with you here. Not that energy doesn't depend on our models. It just depends on them in a very different way. The entropy of a physical system is the Shannon entropy of its distribution of 'microstates'. But there is no distribution of microstates 'out there'. It's a construction that purely exists in our models. Whereas energy does exist 'out there'. It's true that no absolute value can be given for energy and that it's relative, but in a way energy is far more 'real' than entropy.
Potential energy depends on what you set the zero level to, but I agree that this is very different than entropy. In particular, the difference in energy between two systems is well-defined.
