EHX’s X9 series pedals and Boss SY-300 also have good polyphonic pitch tracking.
However, I listened to a step-through of the SY-300 presets and none of them sounded as good as the Enzo tones demo’d so far, though I’m sure it can be tweaked to sound decent… It also costs twice as much. Enzo’s pitch shifting is a nice, unexpected bonus.
EHX’s Synth-9 does not sound good to my ears, and the other -9 pedals are more focused on non-synth emulations (Mellotron, organ).
