I have a peg perego p3. I bought it because it looks nice and is cheap (I live in Germany and only costs 189 euro) my boy is now 9 months old and I cannot take it anymore. The maneuverability of the stroller is quite bad. Sometimes I can't even push through the narrow lanes of a supermarket without knocking the sides) But I would say I am an average-heavy user as I have used it for a couple of holiday trips. My friend who is a light user (only push her girl like half hr every day) says her peg perego is still working fine. I have since changed to a teutonia (think not available in sgp)
I would prefer Quinnny especially if you have a maxi cosy car seat. Quinnny is also easier to maneuver.
