Which one is more accurate: Digital oscilloscope or Analog oscilloscope?
A friend who teaches undergraduate and post graduate electronic engineering complains that the users of oscilloscopes don't understand the limitations. 

He has said "students happily sample and measure signal frequencies that are 'aliased' by digital scopes sampling rate. They expect their analysis and calculations to be correct". He retained quite old analogue scopes for a long time. He believes students make fewer mistakes with analogue than digital. 

I guess part of the problem is the very helpful, apparently definite, measurement that some digital scopes give. If a user doesn't think about what is happening, those displays are quite seductive, but misleading (the illusion of accuracy).

But it is less about the technology, and more about the users misunderstanding the technologies limitations and capabilities.

I would expect the spec of a 'scope to be a good reflection of the equipment capability because they are (mostly) designed to be read by people who understand what the spec means.
