Andoid or windows for tablet?

Which is the better tablet for college students. I'm looking to buy Lenovo yoga book 10.1 inches which comes in both android and windows. I use Microsoft word and power point for writing essays and presentations. I like windows but since i have a laptop should i get the android version of the tablet so i'll have both android and windows. I thinks windows is better when in it comes to multitasking and complex works but i think windows 10 is too slow on tablets and the tablet mode is not really helpful since the Microsoft app store is very limited and is in a big mess actually. In the other hand is using Microsoft word and power point "mobile version" on android the same as using it on windows 10?
