Safest carseat/ stroller for newborn

I am expecting soon and I wanted to personally get the car seat myself instead of asking family members so I could pick out the safest one for a newborn. Also the safest/best stroller. There's so many to choose from and I am wondering what some of you mom's think out there? What's the safest? I'm not looking for the cheapest because as long as it's safe I don't mind splurging on it. Thanks in advance.
