I believe the smooth pull/take-up is different to creep. I actually like smooth pre-travel... the finger is moving and your sight picture reflects this when the trigger actually breaks. Triggers that break from a dead-stop are too much of a surprise for me, however predictable, and often induce a little flinch even with the best of us. I believe that's why a good clean 2-stage trigger works for a lot of us.
Creep I've always thought of as the slope/rounded feeling that a poor trigger can have as it's actually in the process of breaking, after take-up/pre-travel.
But triggers are like people... no two the same.
