The same as using Red Hat's Linux. You get a well supported environment. If you are a Linux shop but want to run on Azure then it makes sense, to me anyway, to go with the best supported OS on that platform.
I love Linux and while I also have some nagging negative thoughts about Microsoft getting so cosy with the Linux world, I also can't pretend I wouldn't be super excited to run a Microsoft Linux on my dev machine and then push to a Microsoft Linux on my Azure instances.
