Unfortunately, the best designs for newborns are not the best for infants and neither are the best for toddlers, and anyone that converts from one age to the other wont be the best for any age.
I tended to go with the peg-perego for the newborn and infant then switch to maclaren at toddler. (3 kids) I liked the handle that swiveled to allow me to see the newborn, also had 4 wheel swivel where you could lock the back wheels. Then switch to forward facing at infant.
