I definitely think that TQ transmissions have their place in the world. Hell, I even see that VW is offering them on some of their models (1.4 T-Roc has 8-spd Tip vs 2.0T-Roc with 7-spd DSG), so I think that the tech has come far enough that they can hang with the fancier units these days. Whenever I hear clutchpacks I think of bikes with the emphasis on lightness and where you can bathe your pack in oil to keep it cool and lubricated.
I have heard of a few isolated incidents of these Multitronic transmissions having issues, but most are few and far between. I've found that, in my experience, reverse gear is quite lethargic though, so reversing up a steep incline feels really wrong, almost like it doesn't have the power to move the car around. Other than that, another complaint is the 'rubber band' feeling on pullaway which isn't really a major one to me, as I am not a robot racer
But, reading up, if you start having judder on pullaway, it means the clutchpack is busy going out. And flashing PRND lights mean an issue with the TCM, usually. And also (anecdotally) they seem to last longer in the petrol engines than when mated to the diesel engines, so I would imagine the extra torque places additional strain on the box.
