Car seats

Hey all! So I’m expecting my third baby, my third boy, yay!

Well anyways, I had gotten the car seat I used for babies 1 & 2 used, and it expires this year. I am currently looking for a new car seat and I’m stuck between two choices, Graco or baby trend. I have a baby trend double stroller that a car seat would click into, and I also have a single graco stroller that a car seat would click into. Any advice? My older boys are 4 & 1 and I was thinking maybe use the double stroller for them and the baby in the single (graco) stroller? What should I go with? Any insight would be helpful! Thanks!

Also, the previous car seat was a graco snugride and I loved it
