I'd say Godot is the Unity of Unreal Engine. It might not have started in the pole position but it's gaining a lot of steam and catching up in strides. With the new Vulkan renderer in 4.0 the 3D performance should make some leaps as well. Not sure yet how it will impact the VR performance but hopefully it helps there as well. I can live with the performance for now but I am still staying at the original 72hz on the Quest to keep a performance buffer (especially since high frequency hand tracking limits the available resources even further)
