I don't disagree with you at all. The .358 and 9.3 are in my opinion far above the smaller calibers. By that I mean 7's and 30's. The 35 Remington is an excellent deer cartridge.
One thing you can do with that 35 is shoot pistol bullets for plinking or varmints and you can't do that with a 9.3 that I know of.
Now there is another cartridge that has quite a following, and it is a good one, and that is the 338-06. Long ago I was torn between the 35 Whelen and the 338-06. I also like that the 358 Winchester is an excellent cartridge and you can have it on a shorter action and lighter rifle.
