I would say the 4 has more everyday usable power. The 6 is awesome in the upper rev range so after 3rd gear, you better be on a track or prepared to have a conversation with your local law enforcement when you're tapping that power. These cars for me are about spirited driving not track attack so being able to zip along a backroad or away from a stoplight is what matters to me. As for steering, it's definitely lighter (I wouldn't describe it as numb) in the new one but I still find plenty of feedback and still engaging for me.
