I've seen a lot of people on here be teased for difficulty expressing themselves. Either people complain "you're using big person words to describe mundane things" when they're aiming for precision or "woah, we don't need that damn wall of text" when they're aiming for clarity. It's like people just want to complain.
What if one isn't possible? Which of the two would you choose?
It sounds like a strange scenario. You can write a lot of text but not make it precise?
I'd say it's better to have it short and precise. It gives you an opportunity to study the details and learn while the long text sounds like it could be more open to interpretation and confusion
