TBH I only liked the HAB for a newborn baby, once bub gets some weight they need something supportive not stretchy.
I used it a couple of times but it was no good for us as Ash was born 5kg, and it hurt to wear him in stretchy fabric. We used a wrap and a mei tai as well as the ergo.

The infant insert is good, but not if you have bigger boobs. Mine were an E and Ash wouldn't fit in the insert because of that so I just froggied his legs. I love the ergo, I use it a lot. I also love mei tais and use them a lot. I've tried a lot of things and I find SSC the best.
