I looked at the ergo and ultimately chose a mei tai. Mostly because my husband and I both wear it and we don't have to worry about strap adjustment since he is 6' and I am 5'5. (You tie the mei tai on so it is custom fit every time.) It also has multiple carry position options, more than the ergo. The only drawback I've found is that when you're putting it on, the straps can touch the ground if you're not careful. My son is now 21 months over 27 pounds and I can still comfortably carry him in the mei tai.
