My take on it is that it is much like other things built in Germany: it’s efficient business-like and functional without being overstated. There’s no “spark” to make it special, but it’s just out to do a solid reliable job and it delivers on that without trying to be special.
The German support thing used to be a lot worse, time was when English support basically didn’t exist, but it has gotten better.
Will also say the devs are pretty happy to come talk to people (one was a regular on TAZ) and there were many enlightening conversations but a lot of people who shouted them down over being told uncomfortable truths (such as the financial implications of running a forum business in the 2020s)
