If you thought the GX was sluggish, it would be interesting what your opinion of the LC/LX would be. The 4.7 in the Jeep is a totally different V8 than the Toyota one, and I think produces more power (I am too lazy to look it up) but isn't near as reliable from what I understand. The 05+ VVTI Toyota 4.7 puts out noticeably more power than the prior version (my seat of the pants observation), but I didn't think I had the funds at the time to get a newer engine (after I spent so much on the Master Cylinder and sunroof, I had the money to get a newer model, but hindsight is always 20/20 or better...)
My GX has great low end torque, but lacks top end umph. It isn't near as awesome as the 4.6 or 5.7, but it suits my needs. I was coming from a 2010 JKU with 37's and the anemic 3.8L minivan motor. The GX is a rocket compared to that POS, even with 5.38's in the Jeep. Before I lifted and put 33's on the GX, it was peppier than now, but I am still happy with it.
On the brake master cylinder, SOME (not a ton, i was just unlucky) of the earlier vehicles with the 4.7 (100's, GX's, Tundra's, etc) would leak brake fluid, which causes the electric motor to go out. They use an electric motor to provide the boost for braking rather than vacuum or hydraulics. For a new part, the price is $2600 or so, then the labor is unreal. Toyota does not sell rebuild kits (or even just the electric motor), so unless you have time and are willing to try some experimentation with your brakes, you have to buy a new unit, or a used unit, and swap it in. Kurt had the same issue on his LC, but he bought a used assembly, put it in himself, then had the dealer finalize the bleeding of the brake system for him. From what I understand, once replaced, it is good to go. I haven't read of anyone having to do it again if they had a failure.
I have heard of exhaust manifold issues too, but I haven't had that problem with mine yet. If I do, I will look to upgrade the whole exhaust at that time.
I went with OME 2884 front Coils which I believe are light or medium, and OME 2896 Rears which I think are the Heavy load springs. I intended to do a rear bumper right away, but still haven't added one... On that note, I LOVE the Hefty Fab Works rear bumper, and that is what I will likely get. I also went with Light Racing UCA's in the front so I could get the alignment dialed in, and Light Racing Rear LCA's to take the abuse of some rocks hits. The rear's were cheap insurance to have something beefier in harms way than the stock LCA's. Cruiser Outfitters hooked me up with good pricing on all my stuff and I am quite happy with how it performs. When unloaded, my rear feels pretty bouncy, but when I load it up with gear, it is smooth. I wish the front was a little higher, and I might put a spacer in to lift the front a little more, but it works for now, so I will leave it until I put a front bumper and winch on it and swap springs.
I don't have a problem with the barn door. I do like the LC having a hatch and tailgate, but the barn door hasn't been a problem for me. I would like to find a way to open the rear door from the inside for when I sleep in the rig, but that's my only complaint.
Here are some pics I have on this computer. I have more, but they are on my home server.
