Graco car seat 4-Ever v. Size4Me

I have a 2yr old(32lbs and 37") and a 9 month old(26lbs and 31") and we were rear ended by a drunk driver who was going 60mph. My car was totaled but thanks to our car seats the babies were absolutely fine. They both had Graco Size4Me seats. Now I need to get them new seats. At first I was going to get the Size4Me's again since they obviously did there job BUT the Graco 4-Ever seats are on sale for $200 this week. Should I get the 4-Ever seats or get new Size4E seats. Do you like the 4-Ever seats? Anything you don't like? I will be getting a new Subaru Forester so any seat will fit comfortably in it. Thank you
