Has anyone used this stroller car seat set or the nuna leaf grow?

So I ordered this and also got another that I know is top rated but wanted to see if any mommas have tried this brand. I also want to know if you’ve tried the nuna leaf grow cause I ordered that as well knowing it goes up to 130lbs and my 3 year old will try sitting in it. If you’ve tried any of them left me know your experience please

This one I know is a good car seat like I said I got one for my last pregnancy as well but wanted to try something else as well this time so I have a back up.
