I don’t know if any hp soaps are great cleaners by themselves. They usually need presoak or a brush to do any real cleaning of road film. The dilution is going to be so high of any detergent coming out of a gun on the hp soap cycle it really can’t do that much on its own.
Way back when there were no presoak or brush options in ss bays, there was a wash rinse and maybe wax cycle. The wash usually was just some detergent to let the customer know soap was going on the car. It could never be put on at a strength high enough to be effective on film.
Even if you start putting a detergent with some more bite on in your hp soap cycle, it can still not be cost effective to apply at the dilution you would need for any real cleaning. That is why presoak is low pressure. I’ve even seen medium pressure presoak set ups and they still can’t be effective on dirt and economical to run.

Yes there are high pH presoaks that clean well and normally don't cause rinse issues. Those chems are more expensive than your normal stuff, but they do work. I use them for my touchless auto and self serve hp soap. Really depends on what type of operation you are striving for. Since you are on this site though, I'm guessing you lean towards the more professional type.
