I noticed also this difference in energy deposited. It increases with proton energy and it is only due to the nuclear interactions (you can switch on or off the inelastic hadronic collisions to check it). At 230 MeV, 205.5 MeV/incident proton is deposited using Geant4, 204.7 MeV with PHITS and 205.6 with MCNPX. At 100 MeV, if I remember well, about 99% of the energy of the incident particle is deposited. I did not investigated which reaction causes this difference, but if you do so, it would be interesting.
