We love our Peg Perego Si. The only downside is the cup holder is on the side and it comes off easily. I would say this stroller really works best for older kids, 2 and up, better. Easy to get in and out, lays almost flat very easily. When sitting up, the canopy covers almost the entire body. Has a great sling under the stroller. Folds very quick and easily, and has a handle to carry. wonderful suspension and smooth to push around. We bought for $70 at a consignment sale, was the best purchase as we have taken to WDW and all over for 3 years now.
We have seen the city mini and I would have considered it if we hadn't gotten the Peg. It is another great option.
