I have the MB Urban (an older model) and it's great. I guess the Swift would be smaller, lighter and slightly more manoeuverable but I haven't noticed a problem with the one I have. I think the size would be the only difference really.
Think about where and when you would use it and that should help you make up your mind...and consider your boot space. I have a Holden Astra and the Urban takes up almost all the room.
I don't think you'd regret getting either of them though.
I also got the carrycot to go with mine and it was awesome. It was so nice to be able to see my baby when he was younger and it doubled as a travel cot when staying with family/friends or if we stayed out later than expected and needed somewhere for DS to sleep.
You can get them reasonably cheap secondhand on trademe in really good condition, often only used on one baby.
Congratulations on your baby!!
