I agree it depends on the writer and their cultural and educational background. Another example is Thucydides (which as also a native Greek speaker, find funny that anglophones pronounce as Thoo-see-dee-dees, but I digress). Thucydides was considered even in eras closer to him than to as as too abstract/verbose.

Meanwhile Plutarch enriches the laconic myth corpus by reporting that the Lacedaemonians were content with replying to a letter with only the words "About what you wrote: no." Writing style is part of the message.

Growing up bilingual, I personally always found Greek more verbose than English even in brevity. It's good for avoiding ambiguity and getting your intent across but sometimes bad for colloquial communication.
