What would you choose 3.55 gears vs Turning radius

What would you choose... 450 turning radius or 350 3.55 gears for max fuel economy? I may be all wet thinking the 3.55 rear in the F350 is going to make a big difference. I really think the tighter...

The 3.55 gears haul and tow just fine. I've no trouble pulling any freeway grade in 6th gear with the camper and a trailer.

But I'd sure like the smaller turn radius. Doesn't the 450 have 19.5" tires, larger in diameter and therefore the final gearing (mph/1000 rpm) closer to the same than it might seem?
