Historically I've been a manual-shift guy, so I was very anti-creep initially (and cross that the annual service fee included such useless features).
But I tried creep and... I like it on the Model S, if only to prevent roll-back on hill starts. Sorry Tesla, I should not have complained!
Sport steering was OK but made for a wiggly car at high speeds. Now I use Standard.
Regen full on, to save brakes, haven't tried regen off.
