Hard one to call really there's so little between them up to now.
Both lost one game, Carlow to Antrim and crucially Westmeath to Carlow. It's been shown plenty of times in these playoff finals that the groups results don't always give a clear indicator in the final.
If I had to choose I would probably go with Carlow who have had success in a final in Croke Park last year winning the Christy Ring.
