You are looking at it overall from decades.
No one disputes that the EPL is the best soccer league in the world currently and has been for some time. That's why the top 8 to win the champions League have 4 EPL teams.
Your point kind of proves mine because the EPL is so difficult from top to bottom that makes everything else harder in other competition.
Bundesliga is top heavy and one team basically wins it every season.
Italy more competitive but overall the league isn't that great.
Ligue one is a joke this the two favorite teams in the world cup have two players that are from that league.
Spain is competitive but who wins it almost every year? Two teams pretty much.
