Best toddler car seat?

BK2-17

My little one is still within weight limit but we’ve reached the height limit on her rear facing car seat she’s been in since birth. I’m looking around for toddler rear facing that can then front face. We have a car so it’s a little tight and another little one joining us in November so they will both need to fit back there. Iv read good and bad reviews on Graco extend to fit and Graco 4ever all in one. Anyone have one they really like that can transition to front facing once she’s big enough? I don’t want to buy another one for that. Thanks!!
