The question on which is the better option between android and windows tablet is up to your personal preference. As far as performance goes, windows has the advantage of being able to manage multiple apps simultaneously without lag. It is also closer to a normal PC and can support most of a Windows computer's functions and software. Android, on the other hand, is a little more polished. With android, you get better interphase for mobile use, and a wider variety of applications to choose from.
