The league as a spectacle is far stronger than the others and the level of competition each week is higher. That's at the expense of overall quality though as the top teams in the other major leagues can run away with their leagues and focus their attention on preparing for European competition. Just look at the goal differences year on year, which is a better indicator than points imo of how strong/weak competition is in a league. For example its a joke in Spain how much difference there is between some of the teams. Barcelona and Madrid frequently get into the 70s and 80s. That just couldn't happen now in the Premier League.
Finally a thoughtful post, I'm not sure that I agree goal difference is a better measure that points, but the fact that teams can relax before playing in Europe is a massive help.
