Ratios of azimuthal angle correlations between two jets produced at large rapidity separation are studied in the $\mathcal{N}=4$ maximally supersymmetric Yang-Mills (MSYM) theory. It is shown that these observables, which directly prove the $SL(2,C)$ symmetry present in gauge theories in the Regge limit, exhibit an excellent perturbative convergence. They are compared to those calculated in QCD for different renormalization schemes concluding that the momentum-substraction scheme with the Brodsky-Lepage-Mackenzie scale-fixing procedure captures the bulk of the MSYM results.
