That's also subjective though. A FWD vehicle does have sharper turns compared to a RWD, but that's assuming I'm trying to beat you at turning normally. A RWD car shines when drifting, so when going around turns I'm be sliding around them at a good speed and leaving the turn at a good speed too. This is the advantage of drifting if you can do it well, you avoid having to slow down when going around turns. Now if you were taking the same turn as me in a FWD without drifting, you would obviously have to hit the brakes and slow down, with drifting I can maintain good speed whilst only hitting the breaks briefly to force my car to lose control on purpose, thus initiating a basic handbrake drift.
A FWD and an AWD car can also drift, but not as good as a RWD. The AWD technically doesn't even drift, it kind of forces its way through corners in a way. As for FWD, yes it can drift, but because you're using your front wheels to push the car and control the dift, this isn't a very favourable thing to do when the whole idea of a drift is to make your wheels lose traction on the road. A RWD car on the other hand uses the rear wheels to push the car whilst the front wheels handle the control, so you're not forcing both tasks on your front wheels.
There's a big thing to note here of course, and that's the skill required in taking advantage of the RWD's drifting abilities. It's a lot harder to master drifting around corners at the optimum level compared to turning around corners with a nice FWD hatchback or something. So if me and you were to race, and I'm trying to drift my way through corners in a RWD whilst you try to just turn through them with a FWD, you would probably gain a big lead on me as my drifts would be too sloppy to race seriously with.
