Anyone who ever had to tune a circuit for a peak or a null
should be on the analog meter side of that discussion.
Those GD blinking digits, you cant tell if the reading
is going up or down.

I know, the analog meter feels easier, but you can read it to perhaps
1 part in 100 while the digital ones resolve 1 part in 1999, the
better ones 1 in 19,999, and if they let you play around inside the
+/- indicator can be zeroed to half a count or less.

If you are tuning to a peak or null an analog meter is the easiest to
use. If you are tuning to a set value the digital meter works best.
Some digitals have the bar under the digits which makes it somewhat
similar to the analog meter.
Not always true.
