Comparing the MDX and LC is apples and oranges - very different. The GX and 4R are very nice sporty true suvs, but on long trips the LX/LC is much nicer. If you are tall and long legged, the GX/4R are weak on thigh support. The LC/LX are nice for all sizes. I am tall and my wife short, so the memory feature on the LX is very nice. The auto suspension leveling on the LX is nice for trips - always handles well regardless the load and no worry about headlights being too high.
You can have oil changes and service on an LX done at a Toyota dealer for much less than at Lexus ($20-25).
