Is 4Matic full time though? Always thought 4 Matic was at its essence a clutch based on demand system. So permanent rwd, with the front axle brought into play when slip is detected or the electronics deem it necessary. If so then as an awd system it's inferior to Quattro which is true full time awd as it has 3 diffs (100% drive goes through the center TORSEN diff) and is a heck of a lot more durable as it has no clutches to wear out or electronics to fail.
Now there are probably many different versions of awd system that come under the 4Matic brand, much like with Quattro. As the system in the G-class is totally different to that in the E-class. But at its essence I'm not sure that the version used in the sedans is permanent 3 diff awd like Quattro is. For example the new AMG 4Matic system can disconnect the front axle completely for drift mode. There's no doubt certain other advantages to a clutch based system, but they are much more complex and reliant on electronics and clutches to function, and hence more likely to fail compared to Quattro.
4Matic = Problematic (you see what I did there?)

Impressive getting out of that drive. I did manage to highside mine stopping in too deep of snow because of some jerk who would not yield when they were the only one with a point to stop to let the other by. Can't beat physics. A few minutes to dig it out with my scraper and it got out, though. No such thing as stuck, only delayed.
