I'm not going to discuss terminal ballistics on humans. I've hunted deer extensively and killed/seen killed hundreds of animals. One thing I can say unequivocally is that any bullet performance is an average. By that I mean the same hit will not produce exactly the same damage every time. Differences in muscle tension, attitude, adrenaline levels all make the result variable. Hitting a bone in a slightly different angle or a slightly different bone hardness may throw the bullet offline.
I don't use FMJ to hunt(illegal and unethical) so comparisons are out the window. What I have seen is the damage done to metal targets by both hunting and FMJ ammo. You would be surprised at the damage a soft point will do. At 300 meters I've seen a 160 grain 7mm Mag bullet penetrate a steel plate that a 30/06 FMJ only dented. A .223 50/55 grain HP/soft point that expands on a varmint blows right through 1/4" steel plate at 100 yards. The 5.45x39 FMJ is extremely destructive on steel targets @ 200 yards but I haven't tried the HP or Vmax versions on the gongs yet.
