I like that azure vpn is fully managed by Microsoft, this allows me to use it without having any worries about my connection or security since everything has been designed in house from start till finish! It's also super easy for customers/end users who are not tech savvy at all as they can utilize their Azure accounts with ease (without needing technical knowledge).
The pricing model of using cloud services could be better but other than price there isn't much else you would dislike unless maybe your needs exceed what MSRP offers? No problems yet so far we're very happy!! We've used several different providers when managing our network traffic including Cisco ASA devices however none compare to how simple AZURE VPN makes things look after getting done something similar ourselves which helped us realize its value right away.
