EBS Unichorus user and Pino devotee here. I’ve had my Unichorus for years, certainly at least 10. IIRC I demoed a few side by side at the time, but the only other one of that test that I can remember was whatever the Boss chorus was at the time and the EBS was narrowly the better one to my ears at the time. One of the advantages of the EBS is that it offers chorus, flange or pitch modulation (just different interpretations of the same basic effect really, but different nonetheless).
