Actually it's usually better in the digital domain for all of those reasons. Most systems these days have minimal transducer processing stuff in the analogue domain and get it into the digital one as quickly as possible.

Analogue systems have a lot of non-ideal characteristics such as drift, thermal sensitivity, parasitic capacitance and inductance, impedance matching problems, insane cumulative errors and manual tuning requirements that don't exist in the digital domain. They are also more expensive to modify, and the price goes up significantly with complexity and speed. Not to mention small and fast is really difficult in the analogue domain thanks to everything being a transmission line.

Any sufficiently advanced analog computer is indistinguishable from a noise generator.
