Which of the birds do you prefer the most?
Which is the most useful in battle?
Which would win against each other?
I prefer Chatot because it was one of the first Pokemon I saw.
Delibird because it is a good spinner in the NU.(Acts sarcastic)
Delibird has Ice moves but, Chatot is faster so either of them.
But, Delibird has the 4x Stealth Rock Weakness so, I vote for Chatot.
