Of those three, I'd choose the City.
I love the look of the Marcie but sold mine for functional reasons: One of the shorter handles always slipped off my shoulder, the long strap was too thin to be comfortable, and the opening to the bag was too small.
The Pandora is a great bag functionally but to me is strictly casual so a little limiting stylistically.
The Bal City is great for both casual and a little rocker glam. The only thing I don't like about it is the strap, so I ordered a long one from Mautto so I can wear my City cross-body. The lambskin is very lightweight but if you want a tougher leather, the metallic edge goatskin is also beautiful.
