Noah,
Space will do spillover in bypass, some call it trails, we call it DSP+FX bypass mode. Space will also do spillover between presets, this is what we call SPILLOVER. So I think we've got you covered.
I'm actually not sure if any other reverb pedal has both types of spillover, there are plenty with bypass spillover, but I don't know of any with preset spillover (or 100 presets for that matter).
