The cartridge 378 WBY-Magnum is also loaded with the same bullets as the cartridge 375 H&H Magnum, and because of its high muzzle velocity allows even more shots at longer range than the cartridge 375 H&H Magnum. I don't know if the cartridge 378 WBY-Magnum is better for shorter distances compared to the cartridge 375 H&H Magnum.
