Stroller + car seat OR stroller + bassinet for newborn-50 lbs

Dalva
I'm having trouble deciding between a a stroller that works with a car seat attachment or a stroller that works with a bassinet attachment.
I haven't found a well reviewed all in one stroller for both car seat and bassinet attachments.
It seems like you have to choose between a great stroller/car seat travel system or a great stroller that has bassinet attachment.
Any recc's for one or the other? If you had to choose one, what would you choose?
