I have a Stokke Xplory, and I LOVE it.
My husband likes the look, I don't. I think it looks like a bastardised office chair. But he's very tall and it has no kickbar to annoy him, as well as a telescoping handle. It sits the baby up very high - great for traffic fume avoidance, as well as giving the baby more than legs to look at. The seat can be laid right back completely flat for naps (has ababy insert for small/younger ones), or very upright, and it has front and rear facing. It's also designed for good posture for the child, with adjustable footrest - kids often look really uncomfy to me in seats where their legs are cramped up or dangling down. It's very slim (we live in a Victorian worker's cottage with a narrow hallway - Quinnys just squeak in, but the walls are marked from such visits...) and it also works as a high chair in cafes and restaurants, as the height is so adjustable. And it has solid rubber wheels, so no punctures!
My mother hated the look of it, but is now in love, just because it's so easy to use. It's hopeless in all terrain, but as an urban pram/buggy IMO it can't be beaten. It's so light and maneuverable, and brilliantly designed - you can use the big wheels to pull it up stairs with no trouble at all. I do, and I have a pretty bad back (Stokke started out designing ergonomic office chairs, I think) in fact I find it easier to go for walks with it than without, tbh.
The downside is it is horrifyingly expensive. (But you can get them for halfprice second-hand on Ebay, or sell yours on to get that back, after use, while benefiting from the guarantee.) We have no car and live in a compact city with narrow pavements, so it's worth it to us - and I'm someone who gets as much as possible second hand, and believes most baby stuff is a gimmick designed to rip you off.
