Just to be fair, it was someone else who brought up the profile of the Sherman, I don't recall who.
As a case in point, the Sherman did several things very well and several things well enough, much like the P40. The Sherman, like the P40 was as reliable as a brick, the inevitable maintenance nightmares that any complex and large piece of machinery will give you aside. Both were extremely rugged and could put up with a great deal of battlefield abuse. Both were great gunnery platforms and were adequately armed for the job at hand. Both suffered at the hands of a capable, well equipped and determined enemy, yet did the job anyway. Where, the two diverged was that the P40 was eventually replaced (though never completely), the Sherman was not. They were both the "tool at hand" and as such "brought the greatest wounds death and destruction to the enemy" when they were needed most. Who could ask for anything more?
