Samsung devices are loaded with malware and AI slop in general. I'd avoid them if you at all care about privacy. Since Google is still missing end to end encryption for cloud data, iOS seems like the only good choice currently.
iOS sends data to metrics.apple.com, metrics.icloud.com, iadsdk.apple.com, etc. a lot. They are much better than Samsung (who send data to Samsung and other parties), but I am not convinced they are much better than Google devices. It's more who you prefer sending your data to.
In the end something like GrapheneOS is the only good choice. Has all the security features of Pixel (which is similar to iPhone) and the tracking of neither.
