Go with the 450 if you're going to do the big tires/wheels.
I had a '12 350 and did the 2.5" spacer up front and a block 1' taller in the rear.
That truck towed great.
However I was not impressed with the brakes when they were really needed.. They were good at first, but pushing the pedal to the floor didn't help....
The truck pulled 18,000lbs fine, but I wound up leaving the stock wheels/tires on it because I didn't want to give up the performance.....

I'd say to do the 450..... and I believe the 450 has bigger brakes in addition to the bigger front axle.
The lower gear will let it pull the bigger tires...
If I remember the 450 was around $7k more than the 350.... I thought that was steep...
