But it doesn’t. For what I’m looking for, it offers less. Far less. Less stability, less support from app developers, less support from manufacturers, less support from the vendor, less polish, a lesser tablet ecosystem, less cross-device functionality.
The Android ecosystem “offers strictly more” in the same way a restaurant’s trash can offers more food choice. Technically true, but I don’t want to eat any of it. I’d rather order off the limited-but-actually-desirable menu.
There are more apps on Android, and the apps do more things. I'm not sure how you came to this conclusion.
> less polish
The productivity apps on iOS are near useless. Then Apple moved to its own Maps, which was a disaster.
> a lesser tablet ecosystem
Android's tablets are called ChromeOS. They are a strictly better experience than iPad, with a built-in keyboard and Linux support.
> less cross-device functionality
Its default cross-device functionality (installing apps on your device from other devices, phone calling, voicemail, SMS, email composition sync, photo sync, document sync, music sync) is strictly better and existed long before iOS had anything.
All of your perceived disadvantages don't exist, and there are many other advantages that Android has on top like system app updates without rebooting, better security, better privacy, better development for your own devices, better web browsers, better car apps, better multiuser support, more app discounts due to app store competition, better gaming through streaming services and emulation, etc.
