Welcome. I live in Northern VA and ride twisty roads in WV at least 3 weekends a month...and I've owned both an FJR and the Tenere.
Two totally different animals. It really depends on you. If you want to only stay on the smooth pavement roads, and you like a bike that is super smooth and refined and incredibly easy to control in the twisties even at pretty high speeds, the FJR is an excellent choice. However if you want to do the bumpier paved roads around here, or even explore the dirt roads and trails, and you like feeling as if you are an important part of the ride than the Tenere is the only choice.
My brief time (1 month) owning the FJR showed me the bike was terrible on bumpy roads. It wants smooth. It was also so well designed that you can throw that bike into a corner pretty fast and it just goes around it effortlessly. Lots of people like that, it's not my thing. Personally I want to feel like I'm in command of the bike and not just a passenger along for a nice ride.
The Tenere is wonderfully well mannered. Can handle long trips, dirt trails and everything in between. It's a blast in the twisties if you have skills for riding the twisties. If you don't, it's still more fun at slow speeds in the twisties than an FJR.
Both are great bikes, but totally different.
