Interesting comparison, although I don't understand the various categories coz they're in German. Congrats on the S for winning this comparison. Their maintained focus of comfort over sporting dynamics keeps them at the top of the pack.
On the other hand though, being absolutely objective, looking at the interior photos of the two cars, the design, the attention to detail, the extra amenities, and the overall 'plushness' and style of the 760Li is much more appealing than the S600. Just look at how the front and rear seats and headrests are more sculptured in the 7er than the S. The rear centre armrest/console looks fantastic in the 7er, but not so special in the S (for their top of the line model). The TV screen, and more importantly, the attention to detail and how they've implemented them (ie: haven't just stuck them in the headrests, but created a whole new back-of-seat sculpture to incorporate the screens). The sleek and stylish look of the woodtrim on the doors looks excellent on the 7er, while in the S it looks like they've skimped on the woodtrim with little thin strips with no sense of style or design. The ugly 'ruffled' style seat pockets for the rear passengers compared to the new-style pockets in the 7er.... it might be knit-picking, but it's all these little attention to detail things which really make the S look outdated, and out-classes. Again, I'm being 100% objective, and if I were - for some heavenly miracle - evaluating these 2 interiors for my purchase decision, the 760Li would score more points coz of all these little finer things. Yeah sure in the end getting in the car, getting behind the wheel and getting a real feel for these 2 road-yatchs would be the deciding factors in choosing one, but the 7er's interior is very very impressive.
