I'd call myself competent with many types of synths. I had a Polysix in the 80's (LOVED having all those knobs!). Sold that to get a DW-8000, which I still own.I was lucky that the band director at my HS was an electronic music freak; I had tons of hands on time with an ARP Oddysey and SEIL DK-something-or-another. I also had(maybe still have?) a DX100, a Kawai K1 (awful to program!), and an Akai S612 (early sampler, with only two controls and a single one-second sample at a time).
I've got a lot of software synths, including the Korg collection, but it the sound feels thinner in a way I can't completely explain.
(Side thought: I taught keyboard at a music store in the early 90's, and half the time people just wanted to learn how to program their synths. I'm glad that people are starting to program their own sounds again instead of just using what the "workstation" provides).
