I've had a baby-style Oyster and I very much liked it so I would definitely recommend it. It looks modern and stylish, it is reallyy simple to fold up and change the mode of, it is quite lightweight and easy to move around, it has a parent-facing mode (I loved this), you can buy colour packs to change the colour of it.
I have also had 2 Silver Cross systems (the 3D and Linear Freeway) and would definitely not recommend them.. they're so heavy and bulky, awkward to get around, don't look very stylish, are difficult to fold down and put back up (especially the 3D), take up lots of boot space in the car etc. xx
