I like the shifting actuation of the MicroShift awfully well. I know I like it better than the Shimano that uses the brake lever and I think I like it better than I would the little wing style release level of the Tourney (or Campy for that matter). I like the rear exiting cables of the later Shimano but that's the only reason I'd go away from the MicroShift 10 speed STI's I have now. I had Claris on my other bike and the MicroShifts are way smoother and more responsive than the Clairis but I'd expect anything above 5700 would be more responsive and smoother than the MicroShift.
