In short it attempts to clamp on less then consistently made products that are out there. Precision isn\'t everyone\'s mantra
Or precision to different standards. As as been famously stated again and again, there are actually quite a number of different \"Acra-Swiss-like\" standards. E.g., Markins plates are just as \"precise\", and consistently so, but are just spec\'d to different standards.
And, for the record, the RRS level clamps do not engage the Markins plates, and all others engineered to their standards.
So, if functional versatility and not being tied to down to any one manufacturer are really important to you, the screw knobs would be the way to go !
You will note that in the past few years

share the same sizing in addition to a few others
I am only aware of markings doing their own dimensions. Who else is using theirs?
Sometimes it its nice to know that it is made the same way every time.
Yes you are correct that markins has chosen to maintain a different geometry. so that only means they won\'t fit the RRS lever lock and that\'s of course is your choice. They do have their own whose design allows adjustment for tension but if you go with that idea and own many varied plates (older ones are an issue) you end up having to adjust for fit each time. In addition giving an adjustability to some users allows for over and under adjustment. As with all tools the use lies with the end user so its the choice that needs to be made.
And in the end you do have the screw. But I personally prefer the lever as it has advantages to my personal and mechanical taste.
