PBE for conformations

 Dear CCLers
 	Has anyone the experience in applying the Perdew group density
 	functionals (PBE in particular) to the conformational analysis
 	of organic molecules and their characteristics related to
 	other functionals (BLYP, B3LYP, WVN etc)
 	Thank you in advance. I'll summarize the answers, if any.
