How does it compare to Electron-TF for non-GUI apps?

I can already use Electron to bypass CUDA and rely on it for exposing WebGL to TFJS. How does Electron manage to work with all kinds of desktop GPUs? Does it use something like Angle under the hood? Or it works differently?

Besides being dramatically lighter and aimed at non-GUI apps that can be written on top of OpenGLES (and I assume having a WebGL backend fo TFJS), how does Node-GLES compare to Electron?

My evolving aim (as of now) is to be able to build TF apps in JS in embedded form factor without relying on NVIDIA specific libraries like CUDA and cuDNN.

I could use some clarity.
