just my opinion...
1. La Liga (Spain)
2. EPL (England)
3. Bundesliga (Germany)
4. Serie A (Italy)
5. Ligue 1 (France)
6. Primeira Liga (Portugal)
7. RPL (Russia)
8. Super Lig (Turkey)
9. UPL (Ukraine)
10. Maybe Eredivise but their European results are awful lately and they will even lose their automatic CL spot
*I'd put MLS around the 10-15 mark world wide, I'll get to my explanation later*
At this moment the only thing the EPL is better than La Liga is their commercial success and attendance when it comes to the lower clubs. On the field La Liga wipes the floor with all European leagues
Had a hard time determining #5 honestly, PSG is better than any of the Portuguese sides but I honestly feel Porto/Benfica are as good as anybody else in the league. However, the bottom half of Portugal are generally poor teams, so Ligue 1 gets the edge
*As for MLS its probably English Championship level which is stronger than most European main leagues outside the top 10. Problem with MLS is the salary cap hinders their spending so its hard to compare them to the European leagues. For example a club like Dinamo Zagreb who are usually whipping boys in the CL have a bigger budget than all of MLS, even LA and Toronto. MLS clubs lack the depth of top European leagues, so on LA Galaxy for example they have guys like Keane, Gerrard and GDS who can easily still play in a top 5 league however their bench players are probably barely Championship level
