zippy or zooper?

[sandclan]

Hi, first time posting. I have 4 children, youngest is 5, and expecting baby girl next month. I have had Peg shopper, Peg tender twin, combi savvy, combi travel?, kolcraft double and assorted cheapies. I am looking to get another stroller for baby and can't decide between zippy or zooper. I want fairly lightweight, and easy to steer. Any thoughts?
Thanks.
