We have the peg perego capsule but only because it is the one that fits on the skate pram.....in all honesty the safe n sound or peg are much of a muchness I think......the pg perego does have a very good levelling system for fitiing in the car however and the man who installed and fitted it for us last week did comment that the peg was his favourite in terms of safety fit and ease of use...so I dunno... we also have a meridian to swap to when he bigger, it will go in DH's car for now for the occasional time he might need to take the boy somewhere.....
