The surf industry being conservative and protective doesn't take too kindly to negative feedback.
Noel has a pretty good thing going, it's in his best interest to keep the positive vibe and ensure the equipment will keep flowing to him.
While Noel seems to say a lot of the same things about the boards he's reviewing, he does hint at shortcomings and potential quirks he feels. They are pretty subtle, but they are there if you're really paying attention.
As to him being too good a surfer to do reviews, would you watch a review of somebody with less skill? Machado rips but I turned off his goofy explanation of the Seaside.
