Perhaps ask Mike from GamesFromScratch to do a comparison video?
One thing that will differ between the engines is the number of support platforms.
But apart from that I believe there are many similarities. Most engines today have long lists of features and they are all quite powerful. But something that usually isn't immediately obvious from a feature list is how it is to work with the engine and tools day in and day out while developing games. What are the pain-points and what are the time-savers of each engine?
We list a few things Defold does really well here:
As a side note and credit to the parent author I really appreciated the work you did and helper libraries you provided (it helped me learn a lot about some of the greater functionality that the defold engine provided. I also think the choices made for this engine were under appreciated at the time (and still are given its lack of notoriety) I thought Kings move to give it a much more liberal licence might have put it in a place competitively (for 2d at least) to Godot, but I guess their momentum and ambition overshadow the great work everyone who has worked on defold (and surrounding communities has done) - not to say godot isn’t an amazing accomplishment in its own right (which it is and their ide alone a testament to the quality of craftsmanship)

I would really like to read a good comparison between the three one day.
