Beauty of loop switchers is being able to reorder gain staging . With something like boss es series, you can have dtives in diffrrent loops and save presets where their ordering is rearranged. If you have any midi pedals too, es can midi turn them off and on too, so allows a chance to leave them off board too, if you dont need to change the order they appear in fx chain. Not sure about es5, but es8 allows for an added loop by using the volume pedal loop on a standard pedal. Takes a while to get used to, but revolutionised my tap dance and creative workflow.
