hello,
I have the Graco Stylus and I am globally happy with it.
the pros: Its affordable, sturdy, has big basket, snack tray, you can choose wether 3 or 5 safety points for the harness.
The cons: you cant remove the seat to wash it, my baby is sweating with this fabric, size of canopy is limited, the lock at the safety belt looks easy to open once baby gets older and I was afraid my baby would manage to open it.
Regarding the car seat, the first months my baby used to have his head flipping forward due to the inclination of the seat itself so I thought a capsule (maxi cosi or so) would have been more confortable. Once he reached four months or so I didnt notice anymore this problem.
I used the travel system the first year with the car seat but now not so much as I got a lightweight umbrella stroller which is more practical to use in bus and metro.
I would advise you to look for the lightweight version of graco travel system if you plan to use it until baby is 2/3 years old.
I think of the Graco Mirage Plus version.
Good luck and happy shopping
