X model offroad capabilities
As mentioned, you'd be surprised what you can do in a stock X. With a somewhat experienced companion to spot you and a buddy to tug you out when you get stuck, you could tackle some pretty decent trails. I did last chance canyon in my Sahara (exact same off-road capability as an X) when it was bone and had a blast! Here are a couple of pics to whet your appetite...

You'll find a stock X very capable. A set of decent tires will go a LONG way to improving upon that. The Rubicon is an awesome package, but Jeep built a reputation for off-road capability long before the Rubicon (package) existed, therefore you can be assured that the JK X and Sahara continue on that path. Going forward you can always mod as needed to do the things you want to do.
A jeep is a Jeep, design for off-road use... I think if you don't plan to do rock crawling you are fine and if you do a moderate lift and more aggressive tires will help. I feel that the driver's off-road experience has much more relevance than the size of your lift...
Might want to take a look at this thread, too.

In my experience, you can get a lot of good wheeling done in an X. The biggest issue you will run into is tires. The stock all terrains basically suck if you get into sticky mud. Beyond that, the only huge difference between the Rubi and the X as far as wheeling goes at the front/rear lockers, but you can get in and out of a lot of stuff without using lockers.
