i like both, but i usually eat chicken more often. though, when i'm near the coast, i like to have fish more often than not. while inland, i like to have chicken...
If i had to chose I would go with fish (since I havent been able to eat fish or other creatures from the sea)
Tuna, it's like a chiken AND a fish... Haha I'd have to go with fish, chicken get's so boring... Mmmm catfish....
