i don't think i've ever bought gear based on reviews alone.
eg. i fancied a longer prime for FF/portraits. the 85/1.8 fell inside my budget easily, i browsed the lens section here for examples, i searched flickr for examples [with a 5D2], seen excellent/impressive shots & sharpness so bought one i couldn't tell you what it's scored in any reviews & tbh i'm not really interested!! it does it's job & does it well
Then DXOMark is right, because that is the highest ranked Canon lens, on the same level as the Nikon 85mm f1.8
So it may be but my point was & remains that I don't care how many points DXOMark gave/give it
