All phones reach a point where people don't support them anymore, on both Android and iOS. However, Android does 2 things right that make it much better in my opinion:

1. Provide the AOSP so the community can provide support for outdated devices via LineageOS/CalyxOS style forked ROMs

2. Give all phones the ability to directly install software packages (even over ADB) so that they can still be used when they lose Play Store support or even once the TLS is outdated.

You're welcome to check if the grass is any greener on iOS, but there hasn't ever been an iPhone with an unlockable bootloader. Once Apple cuts support for your device it's over, which is a possibility that can at least be precluded on some Android devices.
