Default Fuel Petcock Manual On Off Or Vacuum????

Hi,

Recently I had a failed manual petcock leak like crazy. So I am wondering what is suggested, go with the vacuum style or the manual on off.

I have heard that the vacuum style can rob valuable vacuum and also fail to leak into the engine when off.
