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.
