Ha, yeah, I was like "This has digital oscillators..." Although - I had a Kawai K3 that actually had all of its oscillators out of tune. Could never figure out what was wrong with that damn thing and got rid of it for like $50.
You can do way more with the ESQ-1. But the ESQ has a lot of steppy behaviors in the LFOs and envelopes which isn't ideal. It's hard to say to be honest, I think they're both good, but I do think the DW is a little easier to use only because it's simpler. If I could only have one, it would be the ESQ.
