It's easy to manage everything from one place! I like it so far for how simple it is when managing my hybrid infrastructure remotely with other team members/colleagues that don't have access or expertise of AWS tools etcetera.
Nothing really - just make sure you're using all features available before deciding which tool will be your best fit. Manage an entire VPC stack including network devices within our Azure environment without having any knowledge about networking protocols and standards used by different vendors involved.
