What drives have you seen using SATA III? The only one I know of is the Crucial RealSSD C300. And that one has had some problems with drives just dying, so it's a bit of a gamble.
Other than that one, the OCZ Vertex LE is the fastest one. It is quite a bit faster than the vanilla OCZ Vertex, but has a somewhat untested new controller, so its a question of how much you just OCZ's testing. If you want a 100% reliable and tested drive, go for the Intel X25-M 34 nm. That is the fastest one in real world usage which has been thoroughly tested.
The order of speed is:
Crucial RealSSD C300 Sata III > OCZ Vertex LE > Intel X25-M 34nm > OCZ Vertex
So if you want perfect reliability, go Intel. If you want maximum speed, go Crucial. The OCZ Vertex LE is somewhere in between, but there is a limited supply of those, and there won't be produced any more, so you've got to be quick to grab one.
