Favorite Double Tandem Stroller for Twins

Hi, Could anyone recommend a good double tandem stroller (not a side by side double stroller but one with seats one after the other). Does anyone recommend the Kolcraft double tandem stroller or the Graco Double Tandem Duoglider LXI, or the Graco Double Quattro tandem stroller? Thanks, E. (mom to G/G twins 10 months old)
