Not always, but for example in the case of brakes, bigger 4 piston calipers with bigger braking surfaces usually equate to better brake performance and longevity. The F-150 is rated to tow more but does so with smaller brakes...just food for thought.
I'm sure there are small differences. FWIW, there are also small differences between the Tacoma's 3.5l and the 3.5l used in other Toyota/Lexus platforms....The underlying design is fundamentally same. The same holds true for the Ranger's ecoboost.
There are a lot of things Toyota does which I don't turn a blind eye too. I'd like to see more torquey and more efficient engines offered in their midsized offerings. I'd like to see higher payload ratings across their truck lineup. Apple Carplay should have been made standard several years ago. Lots of areas I think Toyota could improve upon.
But longevity and durability aren't among those shortfalls. When the current gen F-150 is ten years old, how will it be holding up? What will it sell for? The answers to those questions don't really matter to a lot of F-150 owners...in years past, Ford, and the other big 2, didn't have a good track record for long term reliability with their 1/2 tons, and to some degree, their 3/4 tons. Maybe that will change going forward. But until that is proven, Toyota owners will continue to buy Tundra's and Tacoma's, in spite of their shortcomings.
