Some are better, Amethyst uses on device translation so it's models are more limited. Damus & nostrudel use online translation. Less privacy, but better results. What I get for your German part: "What does Nostr actually make sense here: I create my notes in my mother tongue German and contribute to strengthening the German community on Nostr or do I write everything in English, because the range is higher and anyway, almost everyone speaks English? Two profiles are no option. Opinions?" Not perfect, but pretty close. I think maybe translating to English is better than translating to other languages with the on device mode. I've seen it be much improved with Android 16 as well, though it still has issues with Asian languages.
