I'm must be one of the younger guys here. I love the new 116610 and the 996. I'll start with the Ceramic Sub. I like the maxi dial, ceramic bezel (the Sub bezel always looked cheap to me, even on the gen) and clasp. The Ceramic Sub bracelet feels much more substantial and quality. I always found it amazing that a watch that cost thousands had such a cheap looking bezel ring and 'tinny' bracelet. I liken it to closing the door on a german import compared to low priced economy car. I'm seriously thinking about buying one. I've actually gone to an AD to try it on, which I've never done before for any other gen. The watch is very impressive in person.
It is hard to believe that by looking at Prsist 928 pictures that the 928 model was designed in the 80's. It still looks fresh and current today. I bought a slightly used 996 C4 about seven years ago. The 996 is a great car, it's the best car I've ever owned. I agree with By-tor, the car is technically better in every way. It doesn't have the soul of a 993 but as a P-car to drive every day a 996 can't be beat.
