A very relevant and undeniable point relating to this topic is not one A brand manufacturer still produces a CRO, why is that ?

I've always thought they were fascinating. If not for the fact that the tubes are prone to failure I'd have looked for one to have in my collection of gear.

The statements above are not definitive but do serve to raise questions about false expectations.

By your comments it is obvious you have only peripheral knowledge of modern DSO and are passing judgment based on Google searches and opinion of digital scopes more than 25 years old....

You also made quite "modest" claim that you "simply know it all" about this topic of oscilloscopes ("And I know the accurate and correct facts."). Which is quite the statement for a person that apparently misses last 25 years of development in this field.. You might know the accurate facts, but only about analog part of it. You are missing several books worth of knowledge on new stuff. 

To make it funny enough, whenever someone asks me about probing with a scope, I send them to your web site. Your pages about that are awesome resource and very interesting read anybody that uses the scope should know... You did GREAT job there.. Thank you for that, in the name of everybody.

But luddism about DSO, is just that. 
CRTs are dead.
If you like them, good for you.
Anybody that have very little money (not enough for a cheap DSO) and can get a CRT scope for few buck should go with that. Any scope is better than none. But those are exigent circumstances.
DSO are the way to go, if you can.

Provide references for your (incorrect) assertions.

Don't create strawman arguments. The context you deliberately snipped demonstrates your entire post is a strawman argument - or that there is a significant issue with English not being your first language. Or I could mention less charitable interpretations...

We could tell a slight difference, but not which was which, nor which was better.

a very poor sample set, for several relevant reasons! :)

I am aware of very competent people that own both analogue and digitising scopes. They are aware of each instrument's characteristics and use the appropriate one.

And what might the two sets of reasons be?

Agreed. Painful. Capturing one off events always was the USP of digitizing scopes.

Having said that I have come across one that works better han I recall, a Telequipment DM63. But digitizing scopes are still preferable.
