I like my Pop, we bought it as a 2nd stroller to keep in the car. I wanted the quinny as a 2nd as we'll be using the Pop as our main stroller soon.
Downside is the breaks get in the way when bumping up and down stairs/curbs - although I have perfected a nifty flick

Good points, comfy, high handles, big hood, parent pocket in the hood, cup holder, multi position adjustable leg rest, reclines with one hand using a strap (I hate those ones with the bits on both sides! iykwim?)
I'm actually using our pop more and more atm and will do for the summer and liking it more the more I use it. We have the Salsa but there are some lovely new colours available.
They say its suitable from birth but I personally wouldnt put a newborn in it, too lightweight and it doesnt lie compleatly flat.
