Myself I prefer some beef in the neck and the ES VOS delivers that along with the vintage feel and tone. The ES 330 VOS with the under wound pickups and large neck just give you the sweetness of a tele but can also deliver a sting of a rattler when desired. I had the ES 330 L nice tone more on the scale with the Casino but with a bit more growl. The ES 330 has more sustain and and much more beef on the bottom end and the high side its just not as thin as the Casino. Many people compare the two Gibson and Epiphone and although there are those who believe they sound the same in my experience believe me they very much don't.
I have a Casino Inspired natural its about 4 months old and a Gibson ES 330 VOS and in the past a Elitist as well.
