Hi,
I think the primary difference between silver and gold is that gold has the complete set of articulations, whereas silver is limited.
I've had EW platinum for quite some time and, to be honest, am not that happy with the strings.
A lof of the samples have clicks and percussive bow noises, and a surprising number of them are completely out of tune. There are whole patches that more or less can't be used.
It's also extremely intensive - Pointless trying to run it on anything other than a dedicated SSD.
I don't know how other suites do it but I find it really cumbersome trying to arrange something with a range of articulations.
I'd shop around, but I'm afraid I don't have any specific recommendations for you.
