After shopping for hours online for just the right stroller to fit my needs.. I bought the Joovy Caboose Ultralight. I love it. It seems to be the lightest one with all the features I "need."
J.U.(Joovy Ultralight), S.S.(Baby Trend Sit'n'Stand),F.P.(FisherPrice)..
First of all..I just don't think the F.P. is in the same category..they tried, but it doesn't sound like they they succeeded.
For me, the J.U. is better then the S.S. though, and this is why..
Some things many are concerned about:
~Size/Weight: The J.U. is quite bit lighter and compact w/o compromising the quality. I love how easy it is to pick up when putting in the car and it folds so compact(I think the neoprene cup holder is awesome in this sense too!).
~Storage: I've read that the F.P. has tons of storage, but you can only use it with one child(so I would just get a cart). I've also read that many don't think there's enough storage for J.U., but there's only a little less then the S.S. I've also read that many have trouble accessing the basket, but I'm not sure why, it has elastic on the sides(I'm not sure if the S.S. does). I've read that many don't think the J.U. has cup holders..it does, they're made out of neoprene, which is good for insulation and they're a little stretchy so it can fit more sizes and keep them snug so they don't move around when going over bumps. Also, it has a zipper pouch on one side and reg. pouch on the other..very nice for keys, cell phone, etc., they don't fly around and make tons of noise.
~Comfort: Okay, now this is where you have to literally weigh your options.. I'm going for the long run and I'm only going to use it if its easy and lightweight. That being said.. The S.S. does have an extra seat, which is good if your older child isn't too long(I hear they don't fit it very long). Some say the J.U. front chair reclines too much for the child in the back to sit comfortable, but it doesn't, and if it were straight up and down, like the S.S., the child in front wouldn't be comfortable(I also read that if you recline the S.S. front seat, the child in back can't sit down). Just have to think about that. I'm not sure if the back seat on the S.S. slides but it does on the J.U. It's good for when the child is older, you can move it back for more leg room and when the car seat is in use(move forward)theres more "back" room to sit up comfortably. I think that although the S.S. does accomodate two younger children better, as the older child gets bigger, that stroller is no longer a bettter choice. The J.U.(to me is going to be more comfortable in the long run).
~Usablity/Manuvering: I hear the S.S. is kind of hard to collapse, where as it is very easy to do w/the J.U. You don't have to remove the car set adapter(although it makes it about 4 in. longer) and its still easy to collapse. Because the J.U. isn't nearly as long, its much easier to manuver. I hear the S.S. is just as long as a double stroller even when the car seat isn't on.
~~Overall: I think it comes down to weight and size because I've heard the same complaints about the comfort of both..apperantly the sit and stand types just aren't good for long trips. When I first got my J.U. I couldn't believe how small it was!..It is just a tiny bit bigger and heavier then my reg. Graco stroller. I can't wait till I don't need the car seat adapter(what an exciting moment), it will be even smaller then it already is!
I hope this helped anyone trying to decide on the two. I tried to cover all the bases. Try to enjoy what you do choose..Both are expensive(the J.U. is quite a bit more, but well worth it!).
