It's horses for courses, I suppose, as the old AVO would be useful when checking some of the vintage stuff where the circuit diagram shows voltages read using such a meter. A digital meter would be difficult to compare without some thinking. As mentioned above, it's too easy to get into a false sense of precision too.
A revelant experience I once had was a 9V battery which gave a perfect voltage at the terminals, measured with a digital meter, but almost nothing when measured with an AVO. High internal resistance or what! Obviously they should be checked under load but how many of us just use a quick meter check.
I use both, although have abandoned cheap digital meters. I have always found them to have issues of one sort or another. I also find that with most modern digital equipment, in general, that there are usually caveats to their descibed functions. Somewhat hidden issues which would reduce the good selling points.
Don't get me onto digital meters for testing Germanium transistors either. I use an old Russian analogue multimeter for that. It works
