There are too many variables to consider when testing lenses to come away with anything clearly definitive. The best test is to use the lens(es) as you would normally and see how it performs under your conditions. What value is a bench test using extremely fine grained film when you're going to be out shooting hand-held with TX? In a situation like that, with good quality lenses, perhaps the lens that feels best - which is balanced well so you can hold it steady, has a focus feel and resistance that suits you, focuses by turning in the right direction (for you), takes a good lens hood, offers a brighter image to aid focusing, or works best with the focusing screen or aids you use, etc., - would be the "best" lens. All those things can affect the final image.
