If there is a tight tolerance and you place some dust or debris in that clearance you have just affected the reading of the tool. Most would probably be content with not checking it before use, But just a quick check with a 5 way manifold hooked to one cylinder would verify that you have the tool operating all at the same readings.
To answer your question I see advantages in both tools, But for simplicity I would say the Morgan is better in that respect. Since I did purchase both and I have not told Sean what I want to do yet I am still considering keeping both.
Yes the simple fix for a small difference in readings is to adjust the nut on the rod, But only after making sure that the brass bushing and rod are clean and free from gunk or debris. As I am sure you know the back of the tool is not airtight and while the engine is running there is air being brought in from the back of the tool and through the brass bushing and the rod. What comes with air flow? Dust does and it can get in the closest of tolerances.
Back when I was building fuel injectors we had a specially ventilated room as the tolerances where so close between the injector tip that any dust would make them stick, But then again that is millionths of a inch there.
Sorry about the rambling on!
