Nah, the Tour's been largely irrelevant over the last 15 odd years. It's little more than a test of whose got the smartest doctor.
Aside from Armstrong every winner from 1996 to now has been disqualified for substance abuse, which is pretty damning.
If you want to see the best cyclists in the world, follow the UCI mtb world cup (complete with British champions in the Downhill) or the Time Trials.
