If you loaded both to the same PSI using the same powder, shot the same weight bullet (say 300gr hardcast) and used the same length barrel, the .45 Colt would be faster. The .44 Mag would be a little more efficient as it would use less powder since it has a smaller case capacity but the .44 bullet would protrude deeper into the .44's case since it would be longer than the .452" bullet, further reducing powder capacity. The .45 Colt would burn more powder but could match the .44's velocity at a lower PSI (and exceed it at the same PSI) plus the bullet would be shorter and allow even more room for powder.
Both work very well, but which ever option you choose doesn't really matter, between them there is tons of what I call performance overlap. It's doubtful that any game animal would know the difference between the two, but it's never a bad idea to side with the bigger caliber bullet.
