Man United got destroyed by Bilbao. Chelsea got destroyed by Falcao. It works both ways.
Would definitely say the BPL Is better for sure. Much more competitive especially in the last few years. Hell last year alone was probably the best premier league season in history so many ups and downs it was unreal and the gap between the big clubs and the smaller clubs is getting smaller and smaller as the years go on. Honestly out squad isn't much better to the one that won and was still consistently getting into the champo league back in the early 2000's but we kept doing it due to less competition while like Segunda said the gap between Madrid and Barca to the other clubs is just getting wider and wider. Wasn't it something like 28 points last year?
Even in Europe over the last decade how many times has the champo league final featured an English team? Since us in 2005 I can only recall 2010 not having an English team. May not have won them all but does show the overall power of the league imo.
In terms of what you find entertaining though is off course personal opinion but really can't see how La Liga is better than the BPL in anyway.
