This depends a fair bit on where you're using your pump. Digital displays are precise and usually very easy to read, but those displays inevitably need powering – and batteries run out. Stashed away in a freezing pack, they're going to suffer sooner rather than later, and there's no point carrying a really accurate pump if it's dead and you have to guess anyway.
Analog dials obviously don’t need batteries, so will always work when you need them (they're no more vulnerable to crash damage than digital, in reality), but dials are harder to read if you trying to be very precise. Forks tend to use fairly low pressures making accurate readings super-important.
Broadly speaking, analog is better for trail use and digital rules in the workshop. Either style will do the job, but if accuracy is of most importance to you, go digital.
