The Microsoft Lumia isn't a phone. It's a whole with different models. So without knowing which you mean.
But the review on the 950XL is rather good, apart from the availability of apps in Windows: http://www.cnet.com/products/microsoft-lumia-950-xl/
But maybe your criteria for "best" are such that the grand is best. You didn't tell.
