Personally I liked both! Dh used the boba and I used the Tula. I definitely like both better than the ergo. Maybe order from a place that sells both and exchange one if you don't like it? But where I am, you can also find a used boba for 50-60 dollars. Tula, pretty much at retail.

I would also get a standard in the Tula if that is what you get. Tula does have better prints.
I am sure if you Google you can find blogs with comparisons too.
