How is it for you actually?
For me, purely to be entertained it'd be:
1. La Liga - don't watch it that often but when I have, the technique there is great. Even sides like Espanyol can on their day play good football.
Athletic Bilbao is a joy on the eye under Bielsa while Betis at home despite having no players I know (bar reserve Santa Cruz) have been great in the games I've seen them (vs Real and Bilbao)
2. Premiership - Some sides like Man U and Arsenal have weakened but they're still balanced when in form. Do have their weaknesses which gets exposed against the real top sides. Generally pretty entertaining and it goes from top to bottom. Norwich-Wigan for example was a good game this afternoon. Teams to avoid watching though are Liverpool, Stoke, Chelsea, Aston Villa, Wolves
and despite being effective, Everton.
3. Serie A - Despite it having the tradition of being a boring league, there have been quite a few fun games in it. Napoli are always fun while Inter under Ranieri are hilarious. Some sides are appalling though like Fiorentina. I like the fact it's the most competitive league though compared to the two previously mentioned.
Have hardly watched many live Ligue 1 or the Bundesliga games in the last few years, so can't really comment.
Bundesliga 2 games are horrid to watch when looking at technique btw.
I'd rank the Eredivisie above them all when it came to entertainment btw. Even VVV are entertaining.
