No doubt the 375 H&H is "more powerful" than the 9,3x62 and the 9,3x74R.
It shoots a little bigger, little heavier bullet, a little faster.

However many people who have used both report no difference in field performance.
Some even suggest down loading the 375 H&H for better results.

All I can say is that I have had excellent success with the 9,3x74R.
