There's no way anyone can really help you decide what to do here. We can offer advice, but until you smell NR, there's no way to know for sure if you'll like it, love it, or hate it. I can tell you that it doesn't smell like Rive Gauche to me, but fougere is a category that covers a lot of ground.
Personally, I think the bottle is a work of art. But I also think the scent inside the bottle isn't for me. I bought a sample, and I'm glad I did. NR is challenging stuff. It's made up of things I like, yet the overall composition somehow brings me down. It smells good, but it's kind of depressing.
Want to play it safe? Buy a sample immediately. It's only a few bucks. If you like the sample, keep the bottle. If you don't like the sample, return the bottle.
