Vertigo,
I doubt any of the arms would be better than your Breuer w. Allaerts combination for what they do best. I owned that match and that is one of the great combinations. Only difference is I went up the Allaerts tree. But... the MC1b mk2 is great in its own right and the upgrade is not necessarily better and there are qualities of the MC1b that are better than the MC2 Finish.
In a nutshell, yes no best but there are great combinations out there. Not all needs to be equal to do a comparison. You just need to compare different great combinations. And yes a phono stage is part of the equation.
