Haven’t played the Caverns, but I have played the awesome Eccos and Hydra - they have a larger feature set like looper, presets, midi, stereo - but also take more attention cognitively and manual reading to dial-in and operate - the two go hand-in-hand. The LPD stuff is meant to be very balanced and very easy to dial-in, very direct. I guess it just depends what you are looking for in terms of price, feature set and complexity!
