4moms momaroo vs. NUNA Leaf?

Danielle • My husband and I are in our 30's and expecting our first child, a baby boy!
Has anyone looked into and/or purchased either baby seat? 
They seem fairly similarly but very different at the same time.
I would like to hear everyone's thoughts/experiences on them.
I find it impressive that most hospital NICUs use the 4moms brand, but the NUNA still seats preschoolers. But do toddlers/preschoolers even want to sit in a comfy baby seat? 
Looking forward to hearing your responses!
