I run mine on sand all the time without issues in 4-High, but the most important question is; are you disabling your ESP with the 5-second button press proceedure? If the ESP is on then the computer fights the wheelspin you need in sand to maintain momentum & causes you to get bogged down.

I'm satisfied with the 3.8, I'm in a Jeep not a race car, if someone doesn't like me accelerating slowly they can go around.
I owned an XJ with a 4.0 for many years, that wasn't the speed demon either. I haven't had the chance to get away anywhere to get my JK on a trail, but on the road it feels pretty similar to me.

This isn't a cheap hobby? And just slapping some tires on there isn't enough. It's not the way it works.
It's all cause and effect.
Cause = add bigger tires without changing gears and reprogramming the computer.
Effect = performance suffers.
You need to:
Change your GEARS!
Buy a Superchips or equivalent.
And use 4lo when off roading! That's what it's there for.

As other have said, it's not a rocket but has more power than you think if you drive it right. I'm running 35s on 3.10s till the 4.88s go in next week and it's sluggish but still capable of keeping with flow on the road, with almost no mileage loss at all. Programmer will help as well.
I'm not gunna tell you what to do with you vehicle tho

Mine is a stock sport manual with 3.73s and the towing package and the little itty bitty tires (for now). It is by no means a rocket but it does the job on the highway. I drove it through the mountains of WV this past weekend and some hills I had to take it out of 6th gear but other than that it does pretty well for a brick. Even running 5th gear 70-75 mph at about 3K rpms I got 20mpg between fillups.
But top down, doors off more than makes up for it.
When I feel the need for speed I drive my Mustang.

Sure. When you just press the ESP button momentarily in 2 or 4-high, the dash light will stay lit however it only disables certain portions of the ESP/ABS/EBD/Traction control system. When you shift into 4-low the system automatically disables pretty much anything except for the ABS & EBD without having to press anything & the chime will sound the the dash light illuminate when you shift the transfer lever into low.
In 4-high however, if you press the ESP button when stationary & hold it down, after about 5 seconds you will hear a chime and the dash light will stay lit & you now have disabled the traction control program, meaning that you can break traction & spin one or more wheels faster than the others as long as you keep road-speed below about 30MPH (if you exceed this speed the computer will reactivate the traction control until you slow down again below 30); the 5 second press needs to be repeated every time the JK is restarted after shutting off the ignition. There is a way to turn it off permanently involving a complicated button press, ignition-key turning & steering wheel song 'n dance
Normally the moment the computer detects one or more wheels travelling faster than the others (indicating wheelspin) it will either apply the brakes to the spinning wheel to slow it down, cut engine power to the driving axles, or a combination of the two. In soft sand (& also mud) it is often necessary to break traction & spin the wheels in other to maintain momentum & keep moving, however with the traction control active the computer fights this wheelspin, resulting in that "bogged down" feeling where you're flooring the gas but you slow down & engine power drops off noticably, giving the feeling that the motor is powerless & you've somehow become stuck in the sand/mud. The first time I ever took the JK in the sand it almost drove me mad (until I did some later research & discovered the traction control disable procedure) as I would be cruising along fine in a straight line but as soon as I tried to turn (and the wheels would break traction in the soft, dry sand) the Jeep would rapidly brake to a halt & I'd lose all engine power.
