I've found that when message boards are always pushing one thing or the other there's behind the scenes incentives or motives. Kind of sucks for guys like me who just want some unbiased advice. It is what is though.. knowing about it solves the problem. I always frequent more than one forum when I get into a hobby.
Its hype, but not always undeserved.
NS makes great boards, good customer service, good warranty, very good build quality. Whether you find a board that is right for you is different.
Arbor is the same, although maybe not as bullet proof (my topsheet is fine even after banging my coda up, but boy is that base soft!)
It's not incentive or motive, its mob or crowd mentality. You can always sort out the wheat from the chaff if you read enough
