Nuna Rava is slightly more compact front to back, extend to fit is second most compact on the market I think when installed upright without the leg extension. Many people complain that the graco harness is hard to tighten. When you want to forward face (FF) the extend to fit has a weird recline rule - if your kid is under 40 lbs, the seat has to be on recline 4 which will make it take up a lot of room FF.

I can't compare but we had the Graco Extend to Fit LE and I feel like it took up a lot of space in our RAV4. We had to keep it in the middle seat so the front passenger wouldn't be pressed to the dashboard. Just swapped out at 2 years for a Diono 3rxt (or qxt, I can never remember) and I wish we had started with this one for the first 2 years - it's narrower at the base and can be edged up so that it doesn't take as much space front to back. But it wouldn't have slotted into our stroller, so there are tradeoffs in each direction.

We have a small car and a tall baby. I’m overwhelmed looking at all the options. Is one of these better than the other?
