Aether Vial.
Counterspell is slower than Vial, which means at least a third of your countermagic is invalidated by it turn 1. You can't rely simply on having the Needle. If I'm forced into a situation where my Counterspells are invalidated by a Vial, Lackey, or even Wizard, I'd rather have access to a Stifle.
Of course, I don't run red, I don't run Counterspell, and I don't run Stifle. That's just me, though.
