Neither. The Peg Perego side-by-side. (I think it's called the Twin Aria.) I bought mine a few months ago, and if I remember correctly, both of the ones you mentioned have 6 sets of wheels, with one set in the middle where the two stroller seats come together. If you step the wrong way, you get tangled up in that middle wheel. DH sprained his ankle on a stroller like that.
