I've just handled both versions of the Maggie bag at the store. The leathers on both are amazing! IMO, the AR one is much better and a nicer price too. The double frame one at NM is EXTREMELY heavy even when nothing is in it - much heavier than the Paddy.
I saw this third Maggie style in the stores and it's sort of medium sized (smaller than the NM frame maggie and larger than the AR one), it has a zip closure over the top and I think that size is great - it's also much easier to get in and out of than the frame style maggie. And of course the leather is just divine!!!
