Good is the most generic positive word in English, and that's exactly its weakness. "Good" can mean well-made, well-argued, well-received, or just acceptable — a listener has to guess which. In a professional setting, saying something is "good" often reads as polite filler rather than a real assessment.
What "good" doesn't tell you
"That's a good case for the new hire."
Good as in logically sound, or good as in it actually persuaded the room to approve the budget? "Good" doesn't say whether the argument did any real work.
What "compelling" adds
Compelling means persuasive enough to be hard to dismiss or ignore — it makes a specific claim about the strength of an argument, not just its quality.
