Although I think the Championship provides better entertainment and I personally enjoy it more, I would have to say Premier League. Any team has to aspire to be the best they can be and the Premier League fulfils that ambition.
Odd poll.
I prefer Championship to Premier League but do not want to see us relegated
This and this. 46 games, non stop matches including mid weeks, away tickets, big fish in small pond, less corporate - there are LOADS of reasons to love The Championship. But, ultimately the thing I liked the most about it was trying to get out of it the right way. Dropping down after a season would seem pointless.
