On my gravel bike I had 38 mm tires. Going fatter would have gained nothing unless the terrain changed from gravel to wild MTB.

 For whatever criteria you deem significant.

Of course. For tires, it's commonly (but not always) rolling resistance in the real world on a specific type of surface. Traction might be another.
Sometimes it can be tricky to specify the criteria or design the tests, but some things are certainly measurable. And I tend to trust measured data more than mere opinions.
