You're probably asking the wrong place, as most are here because they have a big interest in the synth, or already own it. But to give you an answer: it depends. Is is the raw sound that you found uninspiring? With an extra sound engine on the MiniFreak a lot of new territory opens up, but if the basic DNA of the engines is what you dislike, then I'm not certain you will like it. I own both of them, but actually think they aren't all that comparable.
So my best advice would be to try it out in a store, or try it out somewhere with a good return policy, so you can take it for a spin over the weekend at home.
