Both seats will accommodate up to 65 lbs or 49" forward facing. Both have steel reinforcement in the chassis. Both have similar widths. Both install either with UAS or seatbelt. The Britax is slightly less deep though rear facing, which will give you slightly more leg room up front. However, the Peg Perego does have many more colours to choose from, including some leatherettes which are much nicer to look at vs the Britax which is pretty blatantly "fun kid design". Personal choice, I like stuff that doesnt stick out. Aside from nicer upholstery quality on the perego, the build quality for both is very similar and should hold up to 4-5 years or wear and tear if you maintain it somewhat regularly, ie. take it apart and wash it according to manufacturer instructions a couple times a year or if theres puke/major spill.
