Convertible Car Seats--have you used any of these???

Monica • Mommy to a two year old girl and two month old boy 😍😍
So, I woke up in the middle of the night thinking about car seats of all things! Can any of you help me out with your own experiences? This is Baby #2, and I know we will go the Convertible route. My 2yr old has a Recaro which I LOVED, but I just read really unsettling things from Consumer Reports about its use FF. So now I'm thinking about--
Evenflo Sureride 
Graco Size4Me 
Graco Baby Extend2Fit 
Graco 4ever 
Maxi Cosi Pria w/ tiny fit
Diono Radian RXT 
Do you have one of these???? Thank you in advance!!!
