#2 Title race

The title race is supposed to be the most exciting part of the league. One of the main reasons why these two leagues are the most interesting to watch in the world, is that their title races aren't decided before the season has even started.
However, the Premier League has one massive advantage over La Liga: the number of contenders. While six different English teams have a reasonable chance of challenging for the title every season, its Spanish counterpart has had a maximum of three consistent contenders over the years.
Spanish football has been absolutely dominated by Real Madrid and Barcelona, with the exception of Atletico's title in 2014. To emphasize just how differently the titles are contested, you just have to look at the top three sides of each league in the past years.
In the last five years, Real Madrid, Barcelona and Atletico Madrid have been the top 3 Spanish sides in every season. Prior to Atletico's stint as part of the top 3, Valencia finished in third place for three consecutive years.
The last time the same three sides finished the season as the Premier League's top teams, was in 2007. The fact that Tottenham Hotspur and Manchester City have joined the traditional top four in the title race, to widen the race between the top six, shows just how competitive the Premier League as not even the UEFA Champions League places are guaranteed anymore.
