Huh? What gives Nexenta a better advantage over OpenIndiana? They are 
both in the same boat. Both will have to migrate to illumos and move 
away from the last OpenSolaris ON release. Oh, Nexenta has a company 
backing it? Makes no different when both projects will be using the same 
core image. Now, if OpenIndiana resists using illumos, then you will 
have a case for Nexenta over OpenIndiana.
