Same impression for my other buddy's C63 I've driven (it was the older version before MCT).
If the M3 was offered with a choice of MT or standard slushbox automatic, I would not even give the automatic a consideration. The DCT is a very interesting compromise.
Although I do miss rowing my own gears and doing nice heel-and-toe downshifts, I don't regret my choice of picking the DCT
The choice between DCT and 6MT all boils down to personal preference. There is no good or bad answer .
Im sure its super fast and lightyears ahead of a traditional auto, but at the end of the day it comes down to really wanting an actual manual (i.e. clutch pedal and stick shift) or a paddle shifting auto.
