Well I can say that I have owned all 3 of the bows you mentioned. So I can relate some of my personal experiences.

The Allegiance and Patriot are very similar. The Allegiance is a bit faster than the Patriot. Although the Patriot is a touch quieter. They feel identical in hand. They also share the same riser.

The MM is not quite in the league of the Alle and Pat.

I would go shoot them both and discover which draw cycle you perfer and go with that. Once you shoot them both you will know right away which you like better.

That is if you decide to sell the Razortec. Which in its own is a fine bow as well.
