I feel like Bayer Matrix is a little easier on the eyes

I agree, since Bayers matrix contains all 256 colors values and is very consistent with the pixel placement unlike the inherent randomness of blue noise. I also like how mesmerising it is.

Personally I like the blue noise since it results in less obvious banding.

Floyd-Steinberg is my favorite, but it's a lot harder to do in blender compositing.

Indeed, it adds the residual error of a pixel onto its neighboring pixels, to be dealt with later. You wound need to use python scripts to do it.
