As a longtime Haxe gamedev:

- Heaps is powerful and used by two of biggest and most successful Haxe gamedev companies (Shiro Games, Motion Twin, and I guess the Dead Cells spinoff company is a third now)

- HaxeFlixel is friendly and well-documented and used by some smaller but still successful gamedev companies, and is much more popular in the indie and game jam scene (also HaxeFlixel is 2D-only, Heaps is 2D and 3D)

- There's other noteworthy engines, Kha for instance. Also proletariat (Spellbreak) uses an Unreal engine integration with Haxe.

+1 for Kha. I have been getting crazy good performance with the WebGL target. I also much prefer its immediate mode API, as apposed to Heaps’s display list (or scene graph). I was also able to build out a full editor with this fantastic library https://github.com/armory3d/zui
