Yes, they have more dissipation area, but the tire cannot withstand the same temperatures that an internal hub break can. So, if you need a descent enduring break, best go for disk breaks. They can handle much higher temperatures than rim breaks, and they are much better at dissipating energy than internal break.

When you brake, your tire is applying a certain force to the ground - and, conversely, the ground is applying an equal and opposing force to the wheel. If you use caliper brakes, the brakes are applying another force, also to the wheel, but not at the same point. It is being applied approximately one diameter up. This creates a torque, which depends not only on the forces applied, but also on the distance between points of application. Applying the same braking force much closer to the hub, as in disk brakes, means the distance is halved ... as is torque.

Going over the handlebars has more to do with braking power, and any good braking system will be powerful enough to cause that.
