Android os and Windows os. When we came across comparison between them I would like to suggest the common users like students that it is better to have an android instead of Windows phone. Becoz if you are an active gamer if you love changes in your launcher in that case you will be totally get unsatisfied in case of an Windows phone because it is not compatible with as more games as an android can. And finally there is no chance to change the launcher in a windows phone you have to keep use of that permanent windows launcher
