Car seat for city mini

Just
Hi all! My husband and I have decided on the city mini stroller (we love the way it handles and is so light weight/easy to fold). I'm wondering what car seat we should go with? We were thinking Chicco or brittax. I've heard the the Chicco adapter might not work as well as the Brittax? Has anyone used this stroller? Any help/advice/opinions would be greatly appreciated. Thanks!
