I like the small grounds cos they have atmosphere. The big grounds are good if they're full, but that's only a handful of times each year.
Homebush is the worst for sure - rarely full, and too far from the action. Feel sorry for Dogs and Rabbits supporters who have to call this place home.
Suncorp is probably great during Origin, but I've only been there for a couple of club games and it felt sterile and empty.
Thank f**k the Sea Eagles play at Brookvale. Love it. You'd be hard pressed to find a Manly fan who doesn't LOVE Brookvale Oval.
