We can't tell because Apple is a little opaque with the devices that are in the wild, and Pixels are such a small slice of the entire Android population. What we have are only third party accounts of the iPhone population, e.g. https://deviceatlas.com/blog/most-popular-iphones https://deviceatlas.com/blog/most-popular-iphones According to that (maybe selection-biased) source, it looks like the most popular iPhone is the one released the same year the first Pixel was released. We can't conclude anything about which is used longer, but Android app updates are required to target API level 30 I think for Android, which is no longer supported on the first Pixel, so there's probably a pressure that urges users off of that phone. I'd be surprised if percentage-wise, a larger share of Pixel users are on the original Pixel than iPhone users on iPhone 7.
