Both more active and more attractive. The anoncoin devs goal is to create an anonymous currency. There is no marketing, no hype, just steady development. It's an established, well distributed and much traded coin.

We don't know anything about zerocash. My guess is that the main focus of the zerocash team is to make as much money as possible. And it want surprise me if anoncoin with zerocoin implementation will be the best solution.
