I should have said that although I know sharpness isn't all, I do shoot comparable lenses against each other to decide which one(s) not to use. Making these decisions doesn't require formal resolution testing. I sometimes shelve the slightly sharper lens because the not-quite-so-sharp one is sharp enough and has better contrast or is less prone to flare or is simply easier to use.
