<p>After reading about the new <a href="https://disney-animation.s3.amazonaws.com/library/s2012_pbs_disney_brdf_notes_v2.pdf" rel="noreferrer">Disney Diffuse BRDF</a>, I have been wondering if this is currently the best Diffuse BRDF at the moment? How much more of a difference would this make compared to using a Lambertian BRDF? I have heard of other BRDFs such as Hanrahan-Krueger and Oren-Nayar, are these also better? </p>

Cook-torrance is popular these days, it takes micro geometry into account so attenuates differently to lambert.

Disney's BRDF is pretty much the top of the line as far as diffuse BRDFs go, yes.
