All are good but think about what you need before you buy. This one goes heel position automatic. If you use this with kemper - kemper stage has options on how to trigger for example wahwah. It can go automatic off on heel position, toe position or inactivity. I use all my kemper automatisation with this pedal so I need automatic heel position. If you don't need automatic heel, this is a great pedal so get on that doesn't have a spring return in.
Also this one is used with stereo cable so there's no real output and uses only as expression pedal for any pot.
