Longtongsally,
You are spot on in my opinion - My home town there was a saying about 4wd trucks versus 2wd trucks -- that you get 400 feet further into the bog before getting stuck.
I'll add a couple of thoughts that stem from that old saying:
Jeeps* are incredibly capable from the factory. At the end of the day, no matter how many thousands of dollars in mods one spends cash on, you will ALWAYS find a place you just get stuck in or cannot go. There is no jeep in the world that can do EVERYTHING.
(*some -- a Compass is no Wrangler Rubicon, for instance)
That being said, if you have good recovery gear, regardless of your lifts, tires, etc. you can (hopefully) get yourself out of most jams you get into. Then, as you do more adventuring, you find the weaknesses in your platform for your personal type of travel. I heard the other day, a Jeep is like a car made of LEGO - you can make it work for whatever your dreams dictate.
The other piece of the Jeep puzzle is repairability. The further from Stock you go, in many cases, the less repairable your vehicle will get. Note repairable is different from reliable - but reliability also takes a hit.
Thing is, I can go into any one of the thousands of Chrysler dealerships, NAPA stores, Canadian Tire, etc. and get replacement parts for a stock JK. Once I get into mods, that becomes a LOT harder. And if I'm doing a long haul, say over a few thousand miles, I'd hate to have my specialized suspension/brakes/engine parts break and have to wait however-long to get a new one (The more specialized it gets, the more likely it is to be backordered/limited stock etc, based on the law of Murphy -- which is right up there with Gravity it seems!).
The final point is the $$. I can drive a LONG way on the 5K it would cost to lift my jeep higher then it is now. And that really comes down to the adventure experience -- some people really enjoy the prep of a rig which is awesome. Some people enjoy getting out there, even if it's in their Honda Civic Hatchback held together by ducttape and prayer. Some like a mix of both. This hobby should be yours to dictate.
Moral of the story -- Jeeps are pretty awesome as they are. If you get one, figure out what YOU want to do with it and what will give you the most pleasure.
For me, my Jeep is a daily driver/weekend warrior for camping and getting into remote places via Forestry Service Roads and low-level trails. I rarely go with other jeeps, and, with that in mind, I rarely go places that are technical/risk damaging my rig. I do however often have my fiancee and a couple of friends with me and in a 2 door JK, that means storage (rack) was my first priority over a winch. Knowing I do not have a winch simply means there are places I won't even try, but it is on my list -- thing is, it's built for my needs and will expand as those needs expand.
Cheers
