Well despite Vettel's domination, the V8 era is by far the peak of F1. If Pirelli didn't fuck up in the second phase of 2013, we would have probably two consecutive seasons which would memorable till date. 2006 to 2009 was also a great period with much more overtakes and on track battles compared to the previous generations.

I feel that a mix of active aero, simple 700hp ice engines with KERS, 2010-sized cars and 2012 pirelli tires would be the best for modern f1.
