Peg preggo car seat vs uppa baby ?

Hi all just starting researching my best friend loves her peg pretty car seat but has the uppa baby vista stroller. We think we want the uppa baby not sure about car seat another friend of ours has the uppa baby. This is all a bit confusing as so many out there and models. I know the uppa baby comes with a bassinet but I was just gonna be a Fischer price one that has storage at the bottom. I’m not to crazy on the basinet for the stroller. Any recommendations are welcome !
