THE SPY WHO LOVED ME and OCTOPUSSY just aren't in the same league as
any of the 60s Bond films. Not even the same damn
sport (pointless PULP FICTION reference there, sorry about that

).
I've never cared for OCTOPUSSY, but I'll concede (contradicting myself slightly

) that TSWLM comes close in quality to what I'd call the two "lesser" 60s Bond films (THUNDERBALL and YOU ONLY LIVE TWICE), but only close.
Every single Bond film of the 60s is a copper-bottomed classic, with DR. NO, FROM RUSSIA WITH LOVE, GOLDFINGER and ON HER MAJESTY'S SECRET SERVICE in the highest, four-film, category of Absolutely Unsurpassable All Time Greats.
No other decade compares. The 70s had TSWLM, but that's the only Bond flick of that decade widely acknowledged as a classic (I myself prefer THE MAN WITH THE GOLDEN GUN, but I know that I'm pretty much on my own there; and while MOONRAKER has a lot of fans, myself included, it's still generally considered a bit of a dud).
How about the 80s? You say OCTOPUSSY is a classic, Qwerty. I'd disagree, but let's pretend it is. And then there's THE LIVING DAYLIGHTS. Others might substitute FOR YOUR EYES ONLY for TLD, but I think most people would agree that there were two Bond classics in the 80s, or three at the most. LICENCE TO KILL is really only a "cult favourite", and while there may be those who view A VIEW TO A KILL as a masterpiece, I'm sure they're very, very few in number.
The 90s? GOLDENEYE. That's it. I really don't believe that too many would seriously argue that TOMORROW NEVER DIES and/or THE WORLD IS NOT ENOUGH could compete with the 60s films in terms of quality.
No, the 60s is
THE classic era. Absolutely no "if"s or "but"s. You're free to disagree, of course, but I warn you: you'd be wrong.
