Whereas both seasons were dominated by one driver and one team steamrolling both championships. At least the fight behind Ferrari in 2004 was a lot more interesting. We had BAR Honda, Renault, Williams, and McLaren all battling around for podiums and 2nd place in the WCC. The 4 teams behind Ferrari were usually very close and it was difficult to split them most of the time. Button, Sato, Montoya, Ralf, Alonso, Trulli and Raikkonen were all usually very competitive and close to each other.
Meantime, 2011 was dismal not only for the one-sided domination, but the fact that everything behind was also noncompetitive. It was always Red Bull leading, then McLaren followed by Ferrari, then a big gap to Mercedes, and then an even larger gap to the midfield. This is how the pecking order stayed throughout the entire season, and barely changed. The top 5 was always the same, Vettel, followed by Button, Hamilton, Webber and Alonso in whichever order you’d like.
Both were boring years in F1, but the best of the rest battle in 2004 was infinitely more interesting than that in 2011. On another note, as you might know, I’m a big Ferrari fan and I despise Red Bull. Therefore, whatever the case may be, Ferrari domination will always be more tolerable than RBR domination.
