It depends on your needs, ie: are you in and out of a car a lot or do you walk a lot. From personal experience (and ive had a lot of experience with prams/puschairs) my favourites are Silver Cross Linear Freeway and the Bebe Confort Loola. I am in and out of the car a lot and I do sometimes walk, these two met my criteria, as the chassis combined with the car seat made a quick option to pop in and out of the car without disturbing little one, whilst using the main seat/carrycot unit with the chassis if I was having a walk or baby was going to be in the pram for any length of time. Hope this helps. xx
