Is my 135mm f1.8 unsharp wide open?

Made a thread here couple of months ago freaking out about my newly acquired 135mm f1.8 being less sharp than my minolta stf ( https://www.dpreview.com/forums/post/58986332). By chance I just met some guy who owns two copies of the 135mm f1.8, who said he will let me test mine against his.

Is there a point to this or am i just being paranoid? Here are some more sample pictures
