You are entitled to your opinion on how much difference it makes, but even your examples are not as small.
Of those, I would definitely say Mahomes is the best, and 6'3" is not 6'0".
Look, there is no doubt that a smaller QB can be sucessful. To argue otherwise would be silly, but there is a reason there is such a thing as prototypical body types for different positions. It isn't just QBs.
I also think in this particular case, the durability concerns are obvious, and legitimate.
3" is literally minuscule. Prototype is how you end up with Sam Darnolds, Josh Allens and Josh Rosens of the NFL world.
Durability is a concern for any size qb at any time and it has nothing to do with height.
