Well to be fair, they're for completely different things.
NS seems to be more about what's happening in the world of the famous people. You know- What did Henrik throw this weekend, and was there corn in TWall's shit this morning, etc. Also more about the fashion, trends and media end of things for sure. Also more about the lols in the forums Also far less relevant info on snow, weather, gear and the like.
TGR is more about the gear, the skiing and the obsession over both. They will berate you for not searching and making a repetitive thread, as well as haze any newcomer, but if you have at thick skin and don't mind getting razzed at first, you'll be just fine and the hazing will subside faster the less you act like a little bitch about getting ripped on. There is a shitload of actual factual information to be found, and even the hardest questions can be answered there.
All in all, they're simply different animals. I love both but could never leave either completely as they both do things I really like in their own way. Expecting either to just bend simply to please you personally is stupid. you're far better off figuring out what each is good for and going from there.
