I view Vortex as a training site. I take OW students there; I go there when I'm taking cave classes myself from time to time. As a "recreational dive site" I might go there once if I'd never been, but only once.
Now, if you're an instructor looking for a good training site to introduce your class to open water, Vortex is excellent, with several platforms and enough variety to make it interesting - we use it as a warm-up to the Gulf.
The facilities are superb - shelters, classrooms, campsites, picnic sites with BBQ grills, etc...
