Cargo bike design is a bit tribal. You either load on the front, or on the rear. At Paradise we really like the front loaders we sell, as they are nimble and easy to get on with (unlike Dutch Bucket style trikes etc.)
If you are carrying kids, or dogs (or cats?) then you can have a nice conversation with your passenger. Also if you are carrying something bulky then it helps to be able to see your load going through a gap in traffic, and not find out that you don't fit when your load gets wedged behind you.
