Yes speaking of numerical ratios because they are precise and easy to understand.

Straight from the Super Duty Order Guide ^^^^ are correct about 3.55/4.30 in 250 and 3.73/4.30 in the 350. Interestingly, the 6.2 is only available with 3.73/4.30. The 250 with 3.55 also has a lower tow rating than the 350 with 3.73. These lower ratios seemed to start in 2020 with the 10 speed transmission. Me thinks Ford is trying to improve their fuel mileage. It makes some sense that Ford would pick the 250 to try for better mileage since it has a derated GVWR.

Yes, bought a 2021 F250 7.3 and tow a 30 ft 7600# trailer with full fresh water tank rendering a 1200# tounge.
The 7.3 paired with the 10spd transmission has exceeded expectation, especially in steep mountains where my previous 2500 struggled mightily.
In tow mode, the transmission utilizes all gears 1-8 and locks out 9 and 10.
Driver can also lockout gears on the fly making hilly country a breeze.
I chose 3.55 gears and occasionally see over 17 mpg on long highway trips and 10-11 towing in the hills, impressive.
Heavy towing, I'd opted for 4.30 gears.
I'm confident this 7.3 is going to prove to be a very durable engine with low maintenance costs as it's a simple design.
Time will tell but a very satisfied Superduty owner.
The 7.3 is available with 3.73 or 4.30 gears. I canโt see any reason for getting 4.30 gears. I think if I was towing less than 12 k lbs Iโd want 3.73 gears and towing over 12k Iโd probably want a diesel even though Iโm sure the 7.3 would do.

I haven't towed with one but I think expecting 10-11 towing is very optimistic. Fuelly says the average MPG is a little under 12, which would include towing and not. I think Fuelly tends to be pretty close to real world. I'd probably bank on most folks getting more like 8 towing. Obviously driving habits play a big role.
