MB grabs 1st place in this particular ICE comparo:
2017 Audi A6 3.0T Competition vs. BMW 540i, Cadillac CTS V-Sport, Jaguar XF S AWD, Mercedes-AMG E43 4MATIC - Comparison Tests
After reading that, I'd pick the V-Sport if the prices were reversed and the Benz was $15k cheaper. The Benz did not fair well in performance, but did excellent as a commuter car. A very nice Camry indeed, but a little out of league when it comes to performance. Not much AMG going on except the emblem.
What are you buying a performance/sports sedan for if not sports?
But for Benz money, you could get a CTS-V. The V-Sport is the not the serious (AMG?) version of the CTS.
