And the iPad will run i(Pad)OS that is designed for phones and is intentionally hindered to not cannibalize MacBook sales 😉 Samsung at least got DeX that works great in mimicking a desktop UI.
Both can't run desktop apps though that have features missing on their mobile versions so either way no option for some but I can see people living with the compromise for the form factor if they don't rely on these features.

I use android tablet to see tutorials and books so it is not really a productivity tool for me, but since i also use it to not be seated so much time i found necessary that the sides need to be larger or it needs an handle in each side otherwise i am always putting my hands in screen.

The price is fine if it has the full power of those chips, but until you can run desktop apps on them even a 12.9" iPad Pro doesn't make any sense.
