I had similar experiences seeing WWII artifacts and museums in Romania, Hungary, London, Brussels, and Berlin.

In the first 4 I had the most immersive experiences seeing memorabilia and artifacts from the Allies and Axis. Things like uniforms, cars, letters, tanks, jets, war trophies, and so on.

Everything was highly curated, and from the outside, the infrastructure was not so expensive to run. In terms of quality, the military museums of Romania, London, and Brussels are great.

Those places are to feel and have immersion.

In Berlin, there are only a few screens, but they have only some sort of "small billboards" in a version in German and some rough translation to English. Most of the time it is a picture of someone and some legend only.

However in Berlin and Munich, they have something, in my opinion, better than museums that we call as Documentation Centers. In Berlin there is the _Das Dokumentationszentrum Topographie des Terrors_ (Topography of Terrors), and for me the best documentation center is in Munich, called _NS-Dokumentationszentrum München_, which gets into the roots of the regime via the whole buildupand actual documents from leadership, political party meeting minutes, political discussions, and so on.
