I've had my ONR V2 for several years and am considering getting the latest revision I can in place of it. The McKees since 2022 and the Rapid is a relatively recent purchase used once. I rarely use them but the ONR is used on an older vehicle which I don't like to foam or get overly drenched.
Anyway, I thought I would see which one persuades dirt to settle the best.
Three beakers with 256ml of plain tap water and four scoops of muck consisting of sand, soil, compost and sawdust.

In the syringes were 1ml ONR, 1 ml McKees and 2.5ml of Rapid.

Contaminates suspended before products added.

The products added and stirred, after 1 minute, this.

After 2 minutes.

As can be seen, the McKees isn't doing much in terms of letting the dirt settle, the ONR is ahead but the Rapid isn't far behind.
It seems some sawdust and compost remain at the top being very light.

Finally after 10 minutes. There appears to be a point at which things slow down but the main thing is that the ones that encapsulate the dirt and cause it to settle do quite early on which is good.

It doesn't mean one is a better rinseless wash over another but it might be important how you use them. Perhaps not dipping a contaminated item in the McKees for example.
