I have a front basket and rear rack. On another bike I had a front and rear rack, then later swapped to front basket.

I love over the front basket, holds my purse easily, though I want a slightly bigger basket and haven't found the right one yet. Once the load is over 7-10 pounds I prefer it in the back.

Porteur racks are cool but not practical for me. You need a strap and the right kind of bag.

i love my basket because the essentials are right in front. And if I get hot I have a place to put my coat/scarf/gloves. I also have basket panniers and bag panniers to use too for the rear.
