If leasing, I'd go German. If buying, these two are really neck and neck for me and as posited in the article, for different reasons.
I really like the Infiniti, but it has a few irritating omissions that would try my patience in terms of ownership. At least the rear seats now fold (previous gens only had a ski pass thru), but that steering numbness would
me off. I drove my buddy's parents' Q50S Hybrid and really liked the car overall, but the steering was so, so numb.
Still, the Lexus is too tight inside and so I'd probably go Infiniti on this one.
