how accurate is the stock guage cluster?

Most quality "analog" guages these days days are nothing but digital circuits driving needles attached to stepper motors. I would trust an LCD element to be quicker to light than a mechanical motor/needle combo to overcome inertia and get to the right spot....measurable difference, but not by speed of human senses alone. Since it's all digital at some point along the chain, they're only as good as the signals being fed to them (essentially digital pulses themselves pulled from a notched gear/tooth).

For the speedo/tach, the signal is essentially digital in nature. You're getting a square wave back with a changing pulse width, or PWM
Resistance is not necessarily an issue to circuit accuracy, it will depend on circuit design.

I've also seen digital clusters in ralley cars in WRC. Not sure if all of them do, but most. Just argueing against your post about most racing teams using analog clusters.
Spoon uses the stack cluster which is basically more of a fad thing now as the sensor displays and such it has are pretty useless with all the other devices available.
