I tried Never Summer last year for the first time. I had heard a lot of good feedback on their quality, mainly from the guys I splitboard with but everyone raved about their solids as well.
Having about 15 years worth of Burton's (with some Lib's and others mixed in) I was immediately impressed with the fit and finish on the Heritage I bought. No blemishes of any kind, and really an immaculate board. It felt tight and solid and despite it's light weight, it just came off as durable.
After riding it for a season, all my initial impressions were justified. I don't purposely go riding rocks or objects that will wreck a board, however I don't go out of my way to avoid them either. So my boards are subject to a little abuse here and there and there were many times when I expected to see a core shot or impacted sidewall after doing something stupid, only to find the barest of surface scratches.
Everyone has a different priority on what a board should provide them, but I can't not continue to buy NS; they build an excellent product that rides fantastic and handles everything. A couple of friends have also switched to NS after seeing mine in action, and trying it out a few times (because the board was so indestructible, I had no issues with lending it out to friends when I wasn't using it so that board got around!).
While I really do feel people should try something before putting down 5 bills, I bought the NS Heritage simply based on reviews from forums such as this, and talking with the guys at NS. So if you can demo them then totally do that, but if not I'd recommend doing some research and sending an email to Never Summer.
