You can probably achieve very similar results with both. Hot4D has a deformer and an effector, it can apply the foam maps to a vertex color tag. Whilst aaOcean is a deformer and a Shader. Hot4D has a nice looping option now thanks to the work by Valkaari. I haven't had any time myself yet to use these for any project but you can find more info on both on my website.
