Flights with twins and a toddler

What's the best airline to fly with two lap infants and a toddler. My husband and I will be flying to Cancun and have no idea what airline to choose from. We heard United and Delta are best? I know we can't have two lap infants in the same row. What's the best seat configuration between all of us to choose from? We will be choosing a nonstop flight, what's the best time to fly during the day with all the kids morning afternoon or night? TIA
