In all seriousness, Giro>>>>>Vuelta>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> few pages of this >>>>>>>>>>>>> Tour.
Giro had some action on most of the early mountain stages, though gaps got barely created because they mostsly weren't mountain finishes. Then you had a good 20km of action on the Corvara stage, 60km of action on the Andalo stage, that again and a bunch of craziness on the Risoul stage, and 15km of action on the St Anna di Vinadio stage. Best week of racing I've ever seen.
Vuelta had the best GT stage of the year, 2 very good long range attacks by Orica, 3 of the MTF's provided good action, the rest where murito's being murito's. Breakaways weren't great, and sprint stages competition was the worst.
Tour. Even Sagan couldn't even come close to saving it from the last place. I got to see a Dutch guy win 2 stages, that was pretty neat, though if it weren't those 2, it wouldn't be questioning appeal of the Tour de France, I would be denying its existence. All the other entertainment for me was more to do with things happening that you just can't make up rather than good cycling.
