Yes, it’s absolutely useful. You need the logic probe (which I do have, but never use in „standard“ teaching) only if you plan (or need) to monitor more input signals than the analog ones on the scope.
In fact, to demonstrate the very physical foundation of digital computing, it is very useful to use the analog inputs and zoom all the way in to see the slight imperfections in signal transmission.
