Outside of the 130R.
Would you rather have dominant machinery in your first 2 years in F1, but then fade away for the rest of your career (J. Villeneuve). Or have 8 dry years in F1 with only a single win (Button), but finish your career strong in the final 3 years?
*note that both Button and Villeneuve have 1 title and 11 wins, but their careers were the exact opposite.*
