I would get GNR based on looking at your lineup. I will be completely honest, I had GNR SE, after about 3 months regretted selling it. I now have GNR LE, and even through it's not my best (or favorite) pin, there is something really weird about me letting it go again. The best way to describe it is, it's a change of pace and good to play if you are just trying to have a fun evening with the wife/family/friends or just yourself with a drink lol. If I'm hanging out on a Fri, Sat night, I have to get one game of GNR in. Second best 'theme' integration on the JJPs to that of The Hobbit.
Anyhow, for whatever that's worth, I'd say it's a worth addition to a collection that already has some solid B/W and Sterns. As a single pin, or even two pin, no I would not recommend it.
