Cosatto Duet Lite travel or Graco Duosport ?

[Rosewood]

I'm looking for a twin stroller and have narrowed down to the Cosatto and the Graco Duosport. Has anyone used either of them before, whats the pros and cons? I have a 6 mth old and 2 yr old. Any other suggestions? I tried out the combi but it doesnt seem all that sturdy. Thks
