The branching ratio BR(B -> X_s gamma) is a sensitive probe for physics beyond the SM and thus an important constraint for parameter fits of SUSY models. It is therefore highly important to have a good assessment of theoretical and computational uncertainties, including the differences in the implementations and/or approximations used in public computational tools. We perform a detailed comparison of the various public BR(B -> X_s gamma) codes, evaluating the differences of the SM and MSSM results and their dependence on relevant parameters. The impact on SUSY fits is also discussed.
