Which do you feel has an overall brighter prospect for the future?
In my opinion it is XMR, from a technical and team point of view.
However, once confidential transactions are implemented on to Bitcoin, it is hard to see purpose for any other privacy coin.
I'm going to go ahead and say that Monero (XMR) is a much better choice than ZEC.
Why? Because:
- XMR has a more active development team than ZEC
- the XMR dev team is community-oriented instead of profit oriented
- XMR consistently forks to steer away from ASICs
