"Baby Wearing" Opinions

Lynzee • Mommy to Ammarie, born on March 3,2016!
Hello! I'm a FTM, and am looking for some opinions and past experiences from some others on here. 
I bought a couple of slings for my daughter for when I take here out, and I bought my husband the kind that you wear like a front facing back back. 
Opinions on these? I attached some pics of the two I bought for me and the one I bought for him.
