I've never used the Xpander, but the Polaris has an ADSDR envelope shape
which allows a family of sounds you can't easily get with most other synths.
Also, selective pitch bend is pretty unique, although Ensoniq later copied
it. There are a few other goodies, like the linear Hertz detune. These
features will probably have more to do with the overall sound than the kind
of filter chips used.
