We used this car seat for both of our kids. What sold me was the safety ratings for it and the side impact protection. We bought the Britax Preview so we could just snap it in the stroller and go. Using the Companion was pretty easy - we kept a base in both of our cars and it was always easy to get it in and out. The only issue we had with the seat is that it is HEAVY - even my husband complained about how heavy the car seat was. It's also a little bit bigger than the other brands (I assume due to the safety protection) which made it seem even bulkier at times. Overall, you can't go wrong with a Britax - once we were done with the Companion we went to the Roundabout.
