Aside from display preference and whether the gauges are discrete, it
makes absolutely no difference.
By discrete I mean mostly segregated from other systems.
Lighting might be tied to a common electrical source.
The ECU shouldn't get between the sensor and display.
I prefer analog display.
But piping oil to a bourdon tube gauge means absolutely nothing if the
gauge is no good or the piping gets obstructed.
If it's accurate, it's accurate.
Anybody who is concerned about gauge accuracy should test with another
gauge to verify.

The temperature gauge in my 99 Camry sure acts like a fake analog gauge.
I've never had a gauge that was so rock steady. That's OK, it would
probably cause me worry if moved all over the place like real gauges do.
Thanks for the low down.
