Agree 100%, not withstanding that one particular series, the Windies had zero challengers to their number one status until Australia from 89 onwards. Things may look different on paper but having lived through those days, the Windies were crickets version of Ali or Tyson.None really stand out to me.
Not convinced Pakistan was ever that close to West Indies in the 80's. They had a good team but Windies were still clearly number one side in world. Second best was some distance in my opinion. Although that does not mean that a single series was lopsided but in the era itself I never felt any side close to West Indies then.
I think the closest rivalry I enjoyed as in teams quite evenly matched and probably top two in world at the time was after the mid 90's with Australia and South Africa.
The highest standard era for me was the late 70's which was my first introduction to cricket , which was World Series Cricket.
Watching West Indies, Australia and World Xi go at it for two seasons in a row was gold standard.
After that was over Australia probably had some good Tests versus West Indies in Australia but we could never beat them in a series as our batting just was too shallow. But Lillee was such a brilliant bowler you always felt you had a chance. Our openers were not great though so our batting was too vulnerable and our tail virtually started at 8. Against West Indies back then, that meant you were going to lose most times.
But if talking an era where clearly number one side felt like playing number two and not much difference, the closest for me in my time felt the late 90's with Australia and South Africa. It was fun when they had Allan Donald.
