This is the wrong question! You should be trying to determine what is the best project for your investment, not the best regional center. The regional center that is managing the project is a relevant focus for your examination, particularly since regional centers very greatly in the amount of experience they have with the often-difficult immigration aspects of making a successful EB-5 project. But there are good regional centers (generally speaking) that have launched bad projects (one of the largest and most respected regional centers just received a denial of I-526 petitions for recent project), just as there are new centers that have launched very good projects. Plus, in about a third of cases, the regional center is not even managing the project, but instead has entered a profit-sharing arrangement with an outside developer or investment banker that will be managing the project.
