I have Chicco Nextfit Zip and love it. We had an old Britax that expired and loved it also. The new click tights don't buckle into an anchor, they use the seatbelt which I didn't like but it supposedly holds more weight that way. It is rated highly but I think the Chicco is rated slightly higher. Both feature No re-thread harness which I love. I do not know anything about Diono but I've heard good things. This site has great critical reviews of all car seats: https://csftl.org/diono-radian-convertible-car-seat-review/
We have 2 marathons and 2 radians. I prefer the radian because it is better for extended RFing.
