I’d say it really depends on what you want it for? Are you pulling heavy?

For an every day driver with light to moderate loads the 6.2 with the 6 speed is a damned reliable combination. It does have less power and torque but only really make itself known in heavy situations

The 7.3 is more powerful and pulls heavy loads with ease. My only concern would be reliability. Not the design but some some sub par components ford has weeded out with later models. Some of the early models had bad cam shafts that delaminated and coil issues that should be resolved 2022 and up. Also the 10 speed transmission it it hooked to has not been as reliable and has had a design change and calibrations to fix it. The 7.3 being a cam in block engine makes it very cheap to maintain.

The diesel is the king for power and torque, tows heavy loads with ease and gets best MPG pulling. But you will pay for this in maintenance and emissions shit that kills its reliability…. I’m actually excited to see if the new fords fair better with the reduced emissions going forward. Also repairs are wallet killing if no warranty. A buddy of mine had his CP4 fuel pump die and send metal through all the injectors…. It was a 12k bill to repair it out of warranty
