Interesting, I keep this in mind. Personally, I only see the auto modes useful in Stop & Go traffic and highway cruising. Around town, I've always preferred to drive by throttle, so I wanna be in control of the shifts. For example, I prefer to roll up to a stop in 3rd for a much smoother stop than shifting down to 2nd. Comfort Auto does a good job at that, but lacks sufficient engine breaking. Sport Auto is too jerky as it shifts down thinking I'm heading into a turn and want full acceleration out of the turn when in fact I'm coming to a stop at a red light. It must be said that Sport/Dynamic on the RS5 is tailored towards driving on the track or spirited driving on twisty roads. It should also be pointed out, that the S-tronic has two manual modes. Comfort manual is different from Dynamic/Sport manual. The main difference is in the uptake of the clutch from a dead stop for example, and the aggressiveness of the individual shifts. For regular daily driving, I'm settling in on ADS in Auto and the transmission in Comfort manual.
