I have used both genuine Leadshine and the Copies. There is very little difference between them in performance terms. However, the Leadshines are more configurable regards settings if you need to play around with resonance tuning etc. But Digital drives are that good these days you very rarely need to anything with them.

I've used both these on several machines and I'm very happy with them.
