Lion and Mountain Lion are different beasts from all previous OSs. Given that we all concurr that Snow Leopard is the best OS X ever, ML is now pretty stable and quite good.
I switched reluctantly and kept for a while using both OSs (10.6 and 10.8) in two separate HDs.
Now I am on ML 99% of the time and I am quite happy. There are some preferences that let you configure ML to behave more similar to 10.6 than to iOs, but it is true that Apple is still considering whether to move towards a complete iOSification or continuing with this weird mix of OS and iOS.
Personally the only reason why I switched is because of iCloud and the calendar, did not want to switch to Google and did not want to try those unsupported setting to get Snow Leopard work with iCloud.
