Just to add further on my FJR / C14 experience.
The FJR is lighter and easier to manage at low speeds. The new 6-speed gearbox is by all accounts a big improvement as well, so it's probably a draw now in the transmission category. FJR felt stronger down low, the C14 pulls better up top.
My statement on the C14 having better wind protection should be clarified. The advantage to the C14 in this area is minimal and once I had an aftermarket screen on my FJR, I would say it is a toss up. The FJR windshield attachment and brackets are stronger and more robust than C14.
One glaring difference in ergonomics is the C14 has a real tendency to push the rider into the tank. My FJR did not do that.
I think if I were to replace my C14, I'd look at the new FJR1300ES pretty seriously. The problem is at $18K MSRP, it is getting really close to R1200RT money.
Looking forward to the next Gen FJR. It needs a touch more fairing, cornering TC/ABS, and a little bump in power.
