Cogent vs compelling

Compelling is the stronger emotional word: an argument that compels feels irresistible, urgent, hard to turn away from. Cogent is more structural — an argument that is cogent is logically sound and clearly organized, leaving little room for objection. You can find an argument compelling without being able to say precisely why; a cogent argument can be analysed and its structure shown to hold. Compelling pulls; cogent convinces.
