I put 57k miles on my OEM Conti Pro Contacts (car is a 2010 3.6R Limited), with no complaints. They still had some tread left, but winter was approaching and I wanted more than minimal tread for driving up to Tahoe.
I replaced them with the slightly-different ProContact ECOs, which have a higher treadwear rating. All in all they seem pretty similar. The ECO's seem slightly harder, which I don't mind at all. The dry-handling seems about the same, although I've read some reports that imply that the ECO's dry-handling is perhaps a tad worse than the non-ECO's. But the rubber compound used in the ECO's is very good in the rain - minimal degradation in handling and braking distances in going from dry to wet. They are a little quieter than the OEM tires were towards the end of their life (but they were never noisy, unlike some other people's experience).
So far I have 18K on the ECOs. I rotate every 10K, but the wear seems very uniform from front to back (maybe partly due to the 3.6R's 45/55 nominal torque split). I've never had to re-balance, either the OEM tires or the new ECOs. (Also never had steering/vibration issues, despite having an early 2010 model.)
I'm forgetting what other tires I considered getting - I didn't want to pay Goodyear or Michelin prices, but looked hard at a Yokohama tire (not the AVID ENVigor, but some other fairly new model), and also a BFG tire of some kind.
