I'm a wrapper at heart so take my thoughts with that in mind.
The Beco Butterfly is very comfortable and supportive. I've worn my 20lb DD for hours comfortably. There are both pretty and DH friendly fabrics available.
I find my DIY MT just as comfortable and the Beco was a lot more expensive. It's also more $$ than a lot of MT's you could buy.
I seem to be in the minority on this one, but I find it much easier to just toss D on my back then wrap her. Having to but DD in the Beco then get her on my back messes with my flow and feels awkward to me.
Overall I like the Beco and I'm glad I got it, but my wraps and MTs get more love and use but the Beco is the only way DH will wear.
