The MOND models are less accurate than cold dark mater models. As long as MOND fails to explain current phenomina, cold dark matter wins. Period.
I am a fan of the idea that the standard model is incomplete/wrong, but you cannot in good conscience accept a model that fits the data worse all because the current best model has problems.
A proper answer explains why the current model works but is inaccurate. MOND models straight up disagree.
