  The $Q \bar{Q}$ semirelativistic interaction in QCD can be simply expressed
in terms of the Wilson loop and its functional derivatives. In this approach we
present the $Q \bar{Q}$ potential up to order $1/m^2$ using the expressions for
the Wilson loop given by the Wilson Minimal Area Law (MAL), the Stochastic
Vacuum Model (SVM) and Dual QCD (DQCD). We confirm the original results given
in the different frameworks and obtain new contributions. In particular we
calculate up to order $1/m^2$ the complete velocity dependent potential in the
SVM. This allows us to show that the MAL model is entirely contained in the
SVM. We compare and discuss also the SVM and the DQCD potentials. It turns out
that in these two very different models the spin-orbit potentials show up the
same leading non-perturbative contributions and 1/r corrections in the
long-range limit.
