Another vid worth watching is the AutoExpress Focus RS vs RS3 vs Golf R one.
The Focus wins it, RS3 stone dead last. Too nose heavy, too numb, too boring, not worth the extra money over the other 2 was the summary. It basically is all about that engine and cabin quality. The other 2 would run rings around it on a challenging road.
I'd take the Golf personally. The Focus is too harsh suspension wise, the Audi too expensive. As always, the Golf is the perfect middle ground
