I have both and rank them both the same in performance to my eye.....

IMO one would have to have nearly perfect seeing and be using them for planetary observations to have a chance at discerning any visual difference between 1/10th wave and 1/20 wave in a diagonal.

Pretty much the same thing applies to comparing a 1/4 wave (diffraction limited) to a 1/10 wave primary.....it takes pretty good seeing and a discerning observer to detect the difference.
