Goldfinger
Thunderball/Diamonds are forever
Would be my pick of 4 Connery movies, you only live twice would stand out too much between the rest for a cohesive package and never say never again is highly unlikely due to the 40+ year legal battle broccoli & co have endured over it, plus it wasn’t an EON production.
Plus Never Say Never Again is basically a remake of Thunderball so it would be a little redundant and odd to have both.
