Which do you use and why? Which one gets it cleaner. If it matters we have “real” winters here, meaning snow cruft and salt that absolutely must be removed.
Edit to clarify: I’m talking about a choice in automated car washes- not hand washing cars. Seems people are getting confused. Touchless is a few passes with a pressure washer. Soft touch adds spinning car-wash brush things.
With Soft touch you risk that the caked on mud will scratch your paint as it's best of you're car rr that the previous guys mud is still stuck on the soft touch brush. If you have any non stock exterior accessories, they may get ripped off by the car wash as it flails your car clean.
Touch less it's just water cleaning your car. Sometimes you need a scrub. Think of how some things get clean in a mediocre dishwasher and some things you have to scrub clean before that go into the dishwasher.
I'll use whatever's available. Though I have a preference for the soft touch as it cleans better.
