i dono i've got both and have used both in africa a different trips. The 9.3 has a trajectory problem if the range streches out beyond 200 like it does sometimes. and as much as i love my doubles the accuracy level of a good scoped 375 is much better. I find the stopping power of a 375 to be greater than a 9.3, but if i'm worried about stopping power i want my 470. I believe i've taken as much game with one as the other, and what it really boils down to is which one i feel like taking at the time.
