I disagree.
86 was the one I watched the most as a kid, but there are objective reasons for it being the best :
- some exciting teams like Denmark, USSR, Belgium, Brazil and France
- Drama in the Argentina/England game with the hand of god
- the best goal in WC history (Maradona, same game)
- a tremendous final with 5 goals
- what is seens by most as the best WC game ever in the QF (France/Brazil)
- several of the best players to ever play the game being present (Zico, Platini, Maradona, Scifo, Valdano, Giresse, Tigana, Papin, Socrates, Careca, Cesar, Ceulemans, Larsen, Voller, Laudrup, Lineker, Matthaus, Branco, Butragegno, Rummenige, Belanov, Altobelli, Forster and I'm probably forgetting plenty of them) although some played injured (Platini and Zico). All are likely top 100-150 of all time.
- getting rid of the different time games because of Germany/Austria in the previous WC
- Morocco being the first african team to get out of the group stage, finishing on top of England, Poland and Portugal.
