As a fan of a number of AWD cars (coincidental, not because I love AWD), I'd say neutral, but that's only because you can generally tune an AWD car to give you the understeer of an FWD, or the oversteer of an RWD, whereas its nigh on impossible to get an FWD to drift and powerful RWD's will never understeer under power.
So really it depends on the track, one with nice wide corners like, say, Fuji, can be fun with understeer because you can point it in the corner quite deep, get past the apex then pin open the throttle and end up on the outside of the corner without really trying, but for tracks like London it can be more fun to go with a harder compound for the rear tyre, make the rear higher and softer and apply a front brake bias, that way you can put the car in the corner facing the wrong way, swing it round, dab the brakes (very hard) then apply the throttle and it'll go round, albeit a bit slower than if you did it properly but where's the fun in that?
I think I'm getting carpal tunnel syndrome now, time to stop
