I think the delightful PM is a great size. The MM is too big and can get heavy and the GM...well you can fit a small child in there and still have room. The Delightful PM sits closer on your arm as well than say the MM ...Now the totally MM is nice and zips...I know you said it looks like a diaper bag. I thought so too at first and actually sold the first one I purchased because of that but just last week I ended up buying another Totally MM just for traveling because it zips!!
I think next time I go to tge store, I will try the totally. To be honest, I don't think I've seen it in person! I know there's a zip pocket in the delightful, so I'll probably put my wallet in there, but I still don't want anything else stolen. When I saw the news story about the people pick pocketing at my local Target, I just have had a hard time thinking just about anywhere is a target with an open bag!
Tough question. Though I like the look of the Delightful, since you already had a NF, maybe it's time for a bag with a zipper. Totally actually looks better IRL than on the site, so maybe you should check it out at the store. I didn't like it when I saw it online but fell in LVoe with it when I saw it at the store. I personally don't like the look of Bloomsbury.
