I don't like spring reverb, so never really use it unless I have not taken my pedalboard for some reason. I have an analog delay and digital reverb in the loop and can get all the subtle ambience I need without the squishness and loose low end of a spring tank.
Yeah, I'm not a huge fan of spring reverb, either. I don't like the metallic character it adds to a sound. I'd much rather run a decent reverb pedal in the loop.
