Car seat help

Hello, so my 1 year old has outgrown his car seat and I'm desperately trying to figure out what car seat is best, I'm not looking for overly expensive but I definitely want him comfortable and safe. I have an SUV so I'm not too worried about the size. I few that I was looking at were ...

Safety 1st everfit 3-in-1

Graco slimfit all - in - one

Graco extend2fit 3 - in - 1

And Graco Grows4me 4-in-one

It took me months to find the car seat /stroller set but I don't have that time now with doctors appointments coming up etc....so if anyone cane give me some info on their favorite or if any of the ones I listed are good, I'd love for the help!
