I've got a winnie the pooh graco travel system for my munchkin. I like it, except the only thing I don't like, is on the stroller the seat doesn't recline all the way back until it's flat. So I can't really lay her down if we are out somewhere and she falls asleep (not that she ever really does, because she's so nosey, but you get what I mean)
she just retired her infant seat too. So now that's gotta go to storage. She's gonna be 6 months on the 13th, so she's in a big girl seat! But really I think they all push about the same, it's more of what your personal preference is and how often your gonna use it. I love the pink one tho. I would have chosen that one, but my sister in law got this for us...So I can't complain :p
