OP here. I happened to put about 300 miles on my 4r today, in some really crappy weather. Had a lot of time to think about the 4r/LC.
There's one available nearby, and I should probably go drive it either way. But, the 4r has these things going for it:
- Very comfortable on the freeway, cruises all day at 70-80 and returns 20mpg. Cruises better than my old GX470, as long as you don't need to pass on a 2 land road

- 1000lbs lighter than the LC. That's a ton of mass to suspend, brake, etc. I'm sure that's one of the reasons the parts on the LC need to be beefier.
- 4r has more cargo space, and I just hate the fact that the 3rd row isn't removable (easily) in the LC. you can technically remove it, but you've still got seatbelts and other crap back there. Tons of space in the 4r.
- The 4r is the perfect size for me. The LC is only 3" longer and 1.5" wider, but that's probably going to be noticeable.
- I like that the 4r isn't typically driven around my town by soccer moms (no offense, I'm a soccer dad). And, I saw one on the freeway today just like mine and I think they are better looking than the LC200. The LC200 is like a marshmallow.
- And, it's still basically new (10k miles), and I own it. A 2011-2013 LC would be a bit of a gamble, *and* more $$.
Will probably go drive it just to be sure, but today's trip made me love the 4r a bit more...
