My friend, I have been hunting and guiding for half a century, I have made and been present for hundreds of kills, believe me, I know what works in the field. As I said earlier I have a 9.3X62 and have had more than a dozen over the years, I have also had 20 or so .375's... they are both great cartridges and kill game well, but sentimentality aside, the 9.3 is subordinate to the .375... period... to argue differently is asinine. Field experience is anecdotal... you can find an equal number of people to swear one or the other is superior, but ballistic facts are ballistic facts, the .375 H&H is indeed a more powerful cartridge when compared equally to the 9.3X62.
Look... I am not here to kick anyone's puppy... the 9.3X62 is a great cartridge, I like it with 286 Partitions personally... but the .375 H&H is ballistically superior... marginally, but gun nutters love to argue in the margins.
