Baby Jogger City mini/metro are the same. I had a mini and it is a fantastic stroller or pushchair if you don't mind it not rear facing. Full recline and with an adapter can be used with a cabriofix or carrycot.
I have had 6 pushchairs (strollers and tanks) and this was by far my favourite.
The Baby Jogger Micro is basically a more basic and cheaper version of the Mini/metro, it is suitable from 6m as it does'nt recline a lot and the wheels are smaller, and although it is called the Micro it is heavier to lift and to push.
If I could choose I'd rather have teh mini as the larger wheels do make it easier o push and the recline is handy.
The Baby Jogger City Select is more of a BIG pushchair if you don't need to worry about the space and size it would be fab. It can be used as a single with car seat/carrycot/seat option and you can add a doubles kit on to make it a double tandem pushchair for children of different ages or twins.
I personally don't have experience with this but if I had to buy now Iit would be a serious contender aongside the Mini as a stroller.
Overall although I have only had a mini I think it is fnatastic and love everything about it so would highly recommend.
