We same similar taste in rifles! I think that either of these would be an excellent intro into the big bore world. For me, it is a question of nostalgia/class vs. performance/weather-resistance. With respect to terminal performance, I don't expect an overwhelming advantage to the .375 Ruger, but there is some. On the other hand, heavy-for-caliber bullets in the 9.3 have a history of efficacy.
