I have the leupold vx-iii 4.5-14x40 LR B&C reticle on my .270, it's a pretty sweet combo!

If you're gonna get a 3.5-10x I'd go for the zeiss conquest with the z600 reticle or the leupold vx-iii

Just threw a ziess conquest 4.5-14x44 mil dot on my new .243, I think it's a step up from the leupold, very sweet looking, can't wait to shoot it!
