Depends On The Purpose.
Professionally, We Use Only Sony High End Tapes, And Only Once. We Never Re Use Tape Stock.
For Personal Use, eg Just Messing Around Stuff, I Am Fine With Anything Really, Never Had Much Problems With Any Brands Such As BASF, TDK, Panasonic, etc. For Archive Stuff Such As Friends Weddings Or Memories I Want To Cherish For A Long Time I Prefer Using Sony Premium Tapes - Though Nothing Bad Has Ever Happened With Normal Tapes, I Use These Just In Case.
There Is Talk That When Shooting HDV On MiniDV You Should Only Use The Special HD Grade Tape Stock, But Fortunately Since A While I Have Been Fine Using The Previously Mentioned Sony Premium Brand Tapes.
Hope This Helps 🙂
