What's your favorite baby carrier?

K
I'm just curious because I've seen a lot of hype on this. I personally prefer the Ergo baby carrier. 
When my first was born I didn't use one but when my second was born 18 months later, it was a neccesity. I tried several different carriers always going up a little in price and finally found that Ergo was the best for my body type and didn't give me any sort of back pain. My husband just got me a brand new one for my birthday and I'm so excited for baby to come so I can use it!!
