no comparison, as i mentioned throttle, or a clutch kick will push the car in the direction of the drive wheels, depending on the angle, this means it can add a bit of forward speed, as well as speed towards the corner, this is why the angle for this technique is extremely important, a handbrake will slightly reduce speeds and keep the car moving in the direction of the momentum (forward, not into the corner), the angle is not as important in determining where the car goes, hence more angle can be applied.
also, depending on the diff, the torque applied can vary from wheel to wheel, whereas the handbrake (especially with a hydraulic hb) it will be constant. also the torque from the wheels going from 100kmh's or so to 0kmh's is a lot greater than clutch kicking from 100k's to 130k's or what ever, so it will get the tyres loose a lot quicker.
also, from a tyre point of view, hbing is very hard on the tyres, not only from the extra torque, but from concentrating it on one spot in the tyre, you will just rip tyres apart once they are warm with the hb.
