It's not even the most advanced open source 3D engine right now, considering O3DE (a fork of CryEngine) is open and backed by a fair few big players.
Godot (3.5) on the other hand requires a paltry 72.6 MB. Even less if you go for older versions or recompile it without certain features. It comes fully featured with it's own scripting language (or C# if you prefer but that requires extra disk space) and pre compiled builds for distribution with the final product. You can still use C++ if you wish however I've personally never needed to.
Godot may not be the biggest and flashiest engine out there but I find that it uses what it has got very effectively. It's extremely easy for newcomers to set-up (Just click the executable and you're all set. It even has it's own IDE.) and comes pre-packaged with the majority of features that your average developer will need.
For comparison, I'd say that it's the game engine equivalent of "QBE" or "tcc" to O3DE's "LLVM". It packs most of the punch of the latter in a neat little package.

From my minimal experience with it, I'd disagree. What's the biggest (3D) game built with Godot?
There were certainly teething problems with the Switch version but I definitely think it's a good sign when people contracting for a company as big as SEGA are using it.
In that vein however, I ask this: O3DE is a fork of the Amazon Lumberyard engine. Amazon Lumberyard has not been very successful with only a handful of companies using it, mostly Cloud Imperium and Amazon themselves. How do you forsee O3DE changing this pattern?
FWIW, I don't think cornering the non-professional developer market will lead to market dominance. GameMaker is even simpler, and even if it were open source, hobby developers will not be competing technically against thousands of full time, professional engineers working on an engine.
O3DE was a code drop that needed to pick up steam almost from scratch, while Godot has already acquired it over years. Also, they're not exactly targeting the same market segment, O3DE being more of an Unreal Engine-wannabe, which is much more challenging. I wish it well, but it doesn't seem like it's anywhere near "relevant" just yet. It's more like a last chance given to Lumberyard to not fall into total obscurity.
