The power difference between the MT and AT is made up by the gearing eifferences - it's why the AT is slightly faster, the torque curves are better in gear.
The 7AT is a great auto but it's not a DSG, and it does have wierd delays on downshifts, and when you are manually downshifting and aren't aggressive you can be caught by the automatic downshift at stall revs and end up a gear lower than you wanted, which can be a surprise, especially when DRM revs the engine over 5000
