To each their own. My LX was in the shop for just over a a month back in 2015 due to dealer service error they fixed. Anyway I had a GX loaner the entire time. It was great! More responsive, sporty, The “just right” size, Easier to off road (I did take it sheep hunting and on the beach), and drive. I like my LX but For me if I didn’t have a 6800lb camper I’d take a GX over my LX all day.I test drove the GX three times. I really disliked it. Visibility out the back is very poor, due to the thick D-pillars, the generally higher belt-line, and the very thick window surrounds on the rear window.
You either like the barn door or you hate it. I hate it.
The third-row seats in the GX fold "flat" into the floor. In reality, what Lexus did was to raise the rear floor about 5 inches. So when you open the rear door, you will see that the floor is about 5" above the sill of the rear door. This takes up a huge amount of cargo space. If you fold the 2nd and 3rd row of the GX, you get only 60 cu ft of cargo space. In contrast, for the LC you get 80 cu ft. The GX is the right size overall for me, if only it was available without the third row. But it isn't.
The 4Runner is the right size for me and it has 80 cu ft of cargo space (without a 3rd row), but the drivetrain on the 5th gen 4Runner is just horrid IMO. It is also a much less refined vehicle overall (I test drove a 2015 Limited trim several times). Also, you have a Hobson's choice of either accepting a part-time 4WD system and good off-road ability (TRD Off-Road trim) or get the Limited with the proper Torsen lockable center-diff (just like the LC), but have less off-road ability with poorer angles and those stupid 20" wheels. Sigh.
One thing that I hate about the GX is that the rear side panels are molded to fit flush with the folded third row. So it would look like crap if you pulled out the third row.
Finally, I found the drivers seats on the GX to be very uncomfortable. It felt like there was a hard rim around the outside edge of the seat bottom that dug into my thighs.
After test driving the GX 3 times, I test drove a used, 2-year-old LC. Within 10 minutes I knew that I liked the LC much, much better than the GX. YMMV.
