I speak German, Polish, and English fluently and my take is: German is very precise, almost mathematical, there is little room to be misunderstood. But it also requires the most letters. English is the quickest, get things done kind of language, very compressible , but also risks misunderstanding. Polish is the most fun, with endless possibilities of twisting and bending it's structures, but also lacking the ease of use of English or the precision of German. But it's clearly just my subjective take
