Good is a broad positive word. "Good" can mean well made, logically sound, useful, or merely acceptable. Without enough detail, the listener may not know which quality you intend. In a professional setting, a more precise adjective can explain the basis of your assessment.
What "good" doesn't tell you
"That's a good case for the new hire."
Does "good" mean the case is sound, or that it held people's attention? The word does not explain what made the case effective. It does not mean "approved."

Compelling means able to hold strong interest or attention. When it describes an argument, it often means persuasive or hard to dismiss. It assesses the force of the case, but it does not prove that every listener agreed.
"That's a compelling case for the new hire — finance cited the ROI numbers when it moved the request up."
"The data wasn't just good, it was compelling: three separate signals all pointed to the same conclusion."
The first example names an outcome and credits the figures as one reason for it. The second identifies three separate signals as support for its conclusion. In both cases, "compelling" gives a more focused assessment than good.

Instead of: "That's a good argument for delaying the launch." Say: "That's a compelling argument for delaying the launch — the risk data gives the launch owner a strong reason to review the date."
Instead of: "The pitch was pretty good." Say: "The pitch was compelling; two investors asked for a follow-up the same day."
Instead of: "We have good reasons to change vendors." Say: "We have a compelling case to change vendors — cost, reliability, and support all point the same direction."
