Let's put it this way.

Driving a fwd car fast, you need to carry as much speed right up to the turn, jump on the brakes, yank the steering, let the car slide cuz of the weight transfer, apex the turn, then get back on the gas once you're past the apex so you can put the power down and the understeer will help you track out from the turn.

Driving a rwd car fast, you slow down to the proper corner entry speed, turn into the corner, feather the throttle to adjust the line as necessary, apex the turn, get back full on the gas, and unwind the steering. It's a more intuitive process and you're more in control of the car.

That said, you can still go plenty fast in a fwd car, it's just that you have the same wheels both trying to steer and put the power down which makes for a different method of going fast. Either way can be fun. If you haven't driven any rwd cars fast, and you have a nicely set up fwd car, the trail brake, slide, wait til you can get back on the gas, floor it method is certainly entertaining. It's pretty wild. Going to a rwd car I had to adjust my driving, and every once in a while I catch myself trying to throw it around like a fwd car, and that just doesn't work right.

All-wheel drive cars are for the most part pretty understeery too, but they can be made more neutral than fwd cars. They're constantly scrabbling around for traction which depending on the car either means understeer, or neutral. Usually understeer. Those pesky awd car owners try to act like they're in with us rwd car owners just because some of their power is going to the rear wheels.
