Having not done a side by side comparison, my guess is that they will be so close that it would be hard to tell the difference. I'm not sure what the max operating pressure of the .44 is off the top of my head, but I'm thinking it is very near the .45ACPs max of 19,900psi. Both cartridges shoot bullets of similar weights at similar velocity.
If loaded with the same weight bullet at the same pressure, the .45 would likely have a slight edge in velocity, but it would probably be negligible. Personally, I would be surprised if you could tell the difference in recoil.
