The biggest advantage of InWorldz over SL is that builders can work more cheaply there. It costs nothing to import/export. Land tier is cheaper. You can make prims larger and smaller than the max/min in SL. The downside on InWorldz is that it is still, technically, in beta. There is talk about going fully live soon. The population is not very large, yet. PhysX is being added in pieces and should be complete soon. If you are not a builder there is not much incentive to join InWorldz just yet. If you are a builder then the cost savings alone is incentive enough. InWorldz doesn't have mesh yet as far as I know. But for many folks that is not a big deal. If you are just looking to socialize then InWorldz is probably not the place to go yet. If you want to learn to build or are a builder looking to save money then InWorldz is the place to go. InWorldz is constantly being updated so anything I write today is subject to change from month to month. It is a maturing realm whereas SL is "matured".
