The best 'physical' model of computation is probably the reversible 3D mesh (R3M) model: http://iopscience.iop.org/article/10.1088/0957-4484/9/3/005/....

Of course, it depends a bit on what you are trying to model.

Most of the time the different ways to model computing only have a polynomial slowdown to emulate each other. In that sense, quantum computers are different from Turing machines: the best way we know to emulate quantum computers on Turing machines has exponential slow downs.
