The risk of malware is far higher on iOS than on a Google Android device, with Xcodeghost alone infecting more users than all others combined, and oft-exploited system apps like iMessage and Safari requiring a reboot to update. I don't know what you mean by leaks and slowing down (maybe https://www.npr.org/2020/11/18/936268845/apple-agrees-to-pay...), but my point was exactly that this doesn't matter on most Android devices, including Google-flavored ones, because (unlike with iOS) you don't have to use Google's app store or maps or SMS app.
