Help Me Choose a Boutique Phaser

I'm looking at 3 boutique-y phasers that are available near me right now. I need something that does a little more than a classic phase 90 for an industrial project. Trying to really push my pedalboard into the "unheard" territory. Many of my modulation pedals are capable of self oscilating and im hoping for something equally wild from a phaser.

Bass guitar and synths will be run through the pedal. No standard electric guitars in this project.

My used market options are: 1. Strymon ZelZah 2. AllPedals + Spaceman Microdose Phaser 3. Subdecay Quasar DLX (1st edition in purple)

What are the pros and cons of each? If you had to pick one, which would it be? Why? Are there any issues with purchasing these pedals used? (Prone to faulty connections, damage, etc.)

All of these pedals are in good condition available around the same price in the used market in my area.
