I wanted to go with creep off and started that way, but parking in my garage was a major headache that way. I have a very tiny slope, I did not even realize it until I tried to park with creep off. But with that it meant that in order to slowly move the car into the garage, I had to keep switching like crazy between break and go pedal, or use both of them with 2 feet, which felt awkward. Otherwise the car would either start to move too fast for my comfort in the tight space or start rolling backward both of which made me very nervous that I would scrape the car on the door frame.
With creep on it is very easy, I just lightly touch the break pedal and the car moves forward very slowly, easy to control. So creep on gives me 1-pedal parking possibility, while creep off requires high-frequency switching between the 2 pedals.
