FJC and Wranglers are the best off-road toys, money can buy.
If you already have one, I don't see a reason for another car. Your brand new FJC can very well hold weekly drives in stock shape and you should be able to find your peace with that for various reasons:
Off-roading is not all about climbing the fastest or tallest.
Stock FJC will be far more reliable to bring you back home, every time.
Stock FJC, will push you to learn real skills and techniques.
Stock FJC, will hold you back to not to do crazy stupid overconfident stuff.
What most people don't think and see while adding mods, is that every mod adds certain dependability on other parts of the car. So one leads to other failures and for most of your life, you will be busy tinkering with the damage caused by the first mod and perfecting its gain as you spend money for that one mod.
Example: When you add better suspension for 10k, you want to feel its worth and you start pushing the boundaries too fast and too rough. Which results in LCA, UCA, Axles taking immense beating and failing one after the other. You fix all this with another 10K expense and you start with round 2, to push more as now you are 20k down. Now comes the wheels, tires, beadlocks, bushes, bumpstops, drive shaft etc. You sort them for round 3, thinking you covered all and you are eligible for pilot license and then gravity prove you otherwise with nose dive, bent chassis or even write off.
I know above example is very variable depending on the sensibility each offroader have from scale of 1 - 10. But more or less, this applicable to everyone when we want to get into modification world. If you still want, stay between 1-5 scale for safety reasons, at least.
