By "the other big tour" I wasn't emphasizing "other" but instead noting that the Giro is actually (in European's eyes) on a level of close parity to the TdF.
Someone called it a b level tour - not sure you've actually been to a european cycling event if you say this ... the giro is a classic (before this year's race which made it an even bigger classic). Europeans love the giro not just because of the history (Barto vs Coppi) that mirrors the epic battles of the TdF but because Italy as a host country has such a beauty that transcends the landscape itself. Italians love their "tour" but europeans respect it as one of two grand classics.
Now, I'm not saying the Giro is better than, or ranks higher than the TdF - it is close but slightly behind in some ways.
But the giro is by no means a b-level tour. Save that for the Vuelta, the Tours of Romandie, Switzerland, Poland and Germany (great race mind you) or the even lesser (c level) tours such as Eneco, Luxembourg, Belgium,
