The negation would be the bigger perk, really, but then Stun and Silence double for that effect in varying ways.
If you've played FFVI, it negates the spell completely. Now the downside in that game is that Celes draws cure spells her way as well and negates them. The 10 minutes is for balance because, as you said, it's instantly recovering 1 spell's worth of MP and negating that spell. I guess 5 minutes won't hurt the balance much though.
