Giro's been better than the Tour for years. The Tour is way too formulaic in its structure (when was the last time they had a summit finish on stage 4), and has been spoilt by the size of the media & hanger-on caravan. They don't finish at Ventoux or many other great summits anymore because they can't fit the "village" at the top so it only goes to ski stations. The Giro goes anywhere, busses etc have to stay at the bottom of the mountain and riders go down to them after finishing.
The Giro still keeps the race as the most important thing, the Tour doesn't.
