Based on my experience with the Ruger 375 African, I would go with the Ruger. A good idea to check the bedding. When mine was a 375, I had it bedded and had no problems. It's a very handy rifle, very lively to the shoulder, and for me, a great fit for quick shooting.
As the 9.3x62 recoil is certainly no greater than the 375 Ruger, the wood stock should be fine, if well bedded from the factory or glass bedded subsequently, if not.
