Simple Cherry vs. Freshwash

Hey guys, new to this forum. I’ve been pressure washing since 1979. Used to do it as a “requirement” as being a painting contractor. The approach to just pressure washing vs washing prior to repainting, is quite different, so I am learning a lot.
I have a question, has anyone made a serious comparison between Simple Cherry and Freshwash with regards to effectiveness, cost, etc. Couldn’t find anything in the search section. Appreciate any feedback.
