Which do you recommend for this persistent world

I’ve been reading a lot about the differences between electrosever, project darkstar, and smart fox. I am still unsure as to which would best fit my needs. (if this has been discussed elsewhere please direct me, but i have tried searching)

The game I am working on has a persistent world similar to that of farm ville, but I would also have turn based combat. I would like to set up zones for players to interact with each other in. Each player would have there own housing zone but i would like other zones such as market and adventure zones that groups of players could go to and interact in.
