K'tan or Moby or Boba

Amanda • 22. Married 💍. 3 year old son. Due with baby #2 July 5th 2016.
I plan on wearing my baby a ton this time around. Hubs and I are outdoor people all summer long. We live in Georgia where summers are super hot. We hike, fish, & boat! I'd like to know opinions and likes/dislikes on these to help decide which one to go for. If you have any other suggestions of wraps that aren't over $75 im open to them!
