I still have my 2008 FJC.
Last year I went to the dealer with the intent of buying a new 2014 FJC TTUE.
While there I saw the new 4R's. I was taken by the look of the front end on the trail premium they had there. I also really liked the nautical blue color. I test drove a new FJC and the 4runner that day. Went back home and did some research on both vehicles and a couple of weeks later decided I wanted the 4R instead. I had previously owned a 1992 4R that I bought new and sold in 2003, so that might have helped me in my decision.
There are a lot of things I like about my 4R over the FJC: Smoother ride, better gas mileage (about 2mpg better), more creature comforts, more room in the rear and cargo area. I have a 3 year old, and when we took trips in the FJC the wife would have to climb back to help her eat. Once back, she could not get out without me opening the door, which was a pain. I was also concerned about how she and the baby would get out if we were ever in an accident. I've taken both vehicles on 8+ hour drives. The 4R is more comfortable than the FJC.
What I like about the FJC: throttle response, the way the brakes feel, the stereo sounds better, the ease of oil changes, and the engine sounds.
I don't do any 4 wheeling, with the exception of a long dirt road to my brother in laws house, so I can't compare them in that area.
For me I would say if I could get the throttle on the 4R to be as responsive as the FJC it would be the perfect vehicle for me.
