Earlier quoted context omitted.
"Least disappointing experience" is how I would put the better kebab places in Berlin! Shawarma in Tel Aviv is not exactly the same but similar and so much better (of course there's a lot of variability in quality there too, and it costs something like 2-3x as much as kebabs in Berlin). I'm sure you can also get amazing specimen in Arab countries and in Turkey (I don't have first hand experience there).
Ok but I was talking about European cities, and Döner Kebab. You're comparing it to a different dish as made in a country from the Arabian peninsula. It's fine to say that the latter is the better food but it makes no sense in the context of arguing where to get the best kebab in Europe.
Shawarma is basically a variation of the same dish:
"The shawarma technique—grilling a vertical stack of meat slices and cutting it off as it cooks—first appeared in the Ottoman Empire in the 19th century in the form of döner kebab,[1][14][15] which both the Greek gyros and the Levantine shawarma are derived from."
