As a frequent Berlin-Munich traveller, it’s such a joy to now be able to make this route in less than 4 hours directly from and to the city center.
Last month I had to instead take a flight (direct ~1h) but it ended up being more stressful and pretty much taking the same time since you have to add the time it takes to get to the airport and go through security.
Not to mention that the trains are quite comfortable and there’s lot of room to walk or even sit down at the on board bistro for a beer or some food.
