i have the hampstead and i adore it so it gets my vote. i'm not a fan of the thin straps on the neverfull..
Does anyone have a picture wearing a hampstead GM?
I just got the neverfull MM this past weekend to wear as a work bag but now i'm craving something Damier.
It would depend on what you want and what size you are. I tried the hampstead but the structured bottom didnt feel too comfortable.
If you're looking for comfort, the neverfull MM would be comfortable to carry but I heard some ladies had a problem with the drawstring at the sides that keep on slipping. I just saw someone tie both ends together - sort of like a V. You can probably try this, too.
But my vote goes to the hampstead MM!! Hope this helps...
