I agree that the patches sound pretty much identical in both versions. I think oversampling is overrated, even though I did oversample the distortion in my own plugin. The Nord Lead sound is not crazy high fidelity anyways, so any potential aliasing might even contribute to the sound like it certainly does in the JP-8000. Overall if I didn't want the additional features like the new resampled waves or patch management, I probably wouldn't upgrade for $75.
