Sling vs carrier

I think Ergo's a good carrier although a lot of my mummy friends are crazy over Tulas. I would be too but it's so expensive! But unlike Ergo, Tula has a better resale value so I guess that's something to consider. Both Ergo and Tula are relatively easy to wear, but I would say Tula is much more comfortable especially for weathers in Singapore. It also helps that it has many pretty designs as compared to Ergo's standard black/blue/grey colours.
