Recommended 3D physics engine?

As I can’t make BabylonHx to work properly with haxeflixel for now, I am considering to switch to Away3D + a 3D physics haxe library. Has anyone some recommandations on the 3d physics library I should use with away3D? which one would you recommand?

Bullet is a famous 3D engine. There is haxebullet and hxbullet (I have not used them)
