Van Halen's, "Best of Both Worlds" - 1 cd with David Lee Roth as frontman & 1 cd with Sammy Hagar as frontman?

or Def Leppard's, Rock of Ages - THE DEFINITIVE COLLECTION?" I own them both, of course, and it's most excellent tuneage. What would be your choice if you don't already own them? VH or DL? Let me know, thanks, answer carefully and c'ya on the otha side.----------->
