I like Britax for car seats, but LOVE my Maclaren stroller.
I have the britax b- agile, i absolutely love it! It's so light and easy to maneuver around. I did a ton of research before i finally decided on the britax , the only thing i don't like about it is that the car seat that goes with it looks so uncomfortable for my daughter (2 weeks old), im sure it will be fine when she gets a little bigger but right now when i put her in it her head flops to the side, kind of scary the first time i saw it, i thought she had broken her neck :/ but this problem is easily resolved by getting one of those pillow things you can find at babys r us. Also (and this is not a big deal) there is no cup holder on the stroller. Other then that it is a fantastic stroller, I'm super happy with it.
