Which series is ultimately greater, Mario or Zelda? (and why)

[Wyrdness]

Mario is the greater series, each entry of both series is on par with each other in quality but Mario has more that are impactful (SMB, SMB3, SM64, Galaxy duo, Odyssey, NSMB), I even personally prefer Zelda it consistently delivers great entries however outside of LOZ, OOT and BOTW industry impact is not the same as Mario.
