For cylinder head temperature on the UL aircraft digital was far better as you could see the rate of change even if it was quite slow and it was next to impossible to see it in analog. The rate of change at WOT told it all. For my speed indicator the relative position of the disk (indicator) was fine and it's relative position on the scale was important .. not available on the digital readout. One needs to process the numbers.

But for a spedometer in a car analog is better. If it's big enough. Don't need to know EXACTLY what the speed is or iat what rate you're changing but just close to what it is. A digital means you've got to process a number and even for a small fraction of time it's a bigger distraction.

So it depends on the application which one is better.
