Not on a 1:1 basis, they're not, not unless you're slamming on the brakes.
Actually slamming on the brakes involves sliding friction (assuming you don't have antilock brakes). However that stopping distance is even greater because rolling friction is greater than sliding friction.
Antilock brakes actually have two advantages. It's not just about maintaining steering control - if you can maximize rolling friction, you will stop in a shorter distance than if you completely lock the wheels.
