The Steps has a very smooth transition, as good as any that I have ridden (definitely a high-end torque-sensor). Plus, Shimano has provided a lot of user-programmable options to dial it in to your preferences. I must confess I do prefer the more powerful drives, so the Steps is not something I'm pursuing. It provides an acceptable 70-nM (from the reference I just googled), so if that power level works for you, the Steps is as nice as anything out there.
