Having drunkenly talked to German philosophers about this, some of them actually prefer reading him in English.

Heidegger does all kinds of fuckery with the German language, and imposes new technical meanings on words. If you're reading it in English and you come across a loan word from German in italics at least you know there's some fuckery going on, and you don't make the mistake of assuming he's using the word in the same way everyone else does.
