Android as a productive operating system is dead on tablets. iPadOS, Windows, and ever ChromeOS have all surpassed Android as a tablet OS.
That's just Apple's marketing kool-aid. Do you actually use an Android tablet for productivity? Because I do, all the time. It's great. Especially with Samsung's DeX option, but even without it works really well.
It supports mice properly, applications scale well and perform great. The days when applications didn't scale well and left huge swathes of screen space unused are long gone. iPadOS fixes a lot of the iOS shortcomings in terms of productivity but Android is still on-par IMO. Previously it was just way better.
I have an iPad as well and I don't like it as much for actually getting stuff done. If you stay strictly within Apple's ecosystem it's ok. But I'm very multi-OS (I use every mainstream desktop and mobile OS) and Android works way better there.
