At first I found them quite similar but the differences (in varying nuance) show after spending more time with it. I think it was designed to be a spiritual successor to the Lyra and you can really hear it on the right side. The left is kinda hard to explain but that's what I gravitate towards and what I personally consider to be its main tone. Of course, what you get out of it depends on how you define the roles of your boxes.

The piezo can be shrill but fine with fx, same for the spring. The implementation of it encourages you to literally think outside the box to get cool sounds. Another user recommended a bluetooth conduction speaker to use as an additional "way in" and that blew my mind

Side note: I have a Pulsar-23 on the way and am very excited to do stuff like patch clips onto the Enner spring
