Although I much prefer the Ultegra grupo on my road bike for smoothness and feel, the Sora stuff on my commuter has proven to be problem-free. Once I got past the initial adjustments (new bike cable stretch), it hasn't required any additional tweeking for 2 years now. And even my big thumbs haven't snapped off the shift buttons.
