we have a sutemi and are not huge fans, but here are a few reasons. our friend now uses it and is a HUGE fan.
i am very short-torsoed and i think that contributed to the sutemi not fitting well. i've heard this from other mammas too.
we love wearing ds on our backs (which we do now with our beloved kozy -- i know, LONG wait). with the sutemi we couldn't ever get him on our backs by ourselves, which was a big minus.
also, just aesthetically, i didn't like having the straps crossed across my chest -- but it's just a look thing.....
i'd look in some of the archives here, although i think they might be in the toddler or life with a babe threads to see what others have said.
good luck deciding!
