This is a great question, one that we did not know the answer till you raised it
Doing an honest comparison both plugins have similar features, but also different feature sets. Shown below are the differences from simple screenshots.
We would preface this, with the WGD Plugin, like all our plugins first comes from a internal business need / client requirement, and regularly gets tested, improved. So usually the changes / improvements to the original MIT code, are made because it has become a requirement somewhere in the organisation.
And from there, we are constantly wanting to make sure our plugins meet the needs of the community. So if there are changes you like to see and are within our roadmap / reasonable, we will add.
