If JM Marquez, Morales and Barrera all retire today, who leaves the best legacy behind?

I think that Marquez is the best fighter of the three, he is very versatile and clearly the best boxer/counter-puncher out of all of them. In terms of legacy, that one is difficult but I would have to say that Barrera is the slight favorite in terms of what he has accomplished. Marquez is definitely my favorite because I think that he is the most talented of the bunch, but was always overshadowed by the other two until recently which made me root for him a lot.
