Of the two you mentioned, the 3.5-10x40 for sure. Last year, I mounted one on my daughter's 7mm-08, as she wanted a little more magnification for the shooting games at our Quemado get togethers. I was surprised to find that I actually kind of like the way it feels, and I darned sure like the way that it shoots. It's more scope than I use on my hunting rifles, but my grandson used her rifle and scope to take a cow elk this fall at a little over 300 yards, and now he wants one for his .270.
