The best thing I like about the portal is the UX. The interface is very user friendly, where in you can view all your projects and the API's google offers. There is also a way of calling the API through the portal itself just to test out how it works. Also you can view all your requests/traffic for any project you created through the developer console.

I feel the errors that the API's throw out are too generic. They can be much more detailed. Review collected by and hosted on G2.com.
