Premier league. Champions league is just a glorified cup competition for me. Great achievement to win it. But can also involve luck . And I hate the fact the possibility of penalty shoot outs can decide the winners. Not so in winning leagues.
I couldn't care less about the European cup, whatever format its in. Give me the Full members/Simod/Zenith or Anglo-Italian cup anyday.
It depends on context - in a really competitive league then probably the league. For Man City it's the Champions League. 2nd in the league would be underachieving with their squad and resources. Which is why it's hilarious when they **** the CL up every year
