VAST-F/toOpenMP vs PGI auto-parallelization

Could you sombody who knows the VAST-F/openMP tool compare it with PGI fortran compiler auto-parallelization feature from the computing performance point of view?

More info about VAST-F/toOpenMP is here:

and here

Some fortran gurus recommend this tool as a superior OpenMP parallelizer on source code level!?
