I'm demoing Q-Clone right now and considering purchase only because Henry Olonga includes presets in some of his products and the thing is on sale right now.
I wouldn't say Q-Clone is superior to any Nebula EQ libraries I have from my experience with it so far. I still am putting other presets before and after the Q-Clone instance, like a EQ IN and EQ OUT preset to make up for what it doesn't provide that Nebula does. Just another tool option to use to have at my disposal.
