Would The Godfather part 2 have been better if Clemenza appeared instead of Frank Pentangeli as originally planned?

It is fairly well known that the role of Frank Pentangeli in The Godfather part 2 was originally supposed to be Clemenza, which did not happen due to the actor not returning for various reasons. I’m undecided on whether or not the movie would have been better if it was Clemenza instead of Frank, so I figured I would ask here.
