I'm not an expert and have not yet worked with splats, however I understood that unlike super-sharp-edged triangles they can represent complicatedly-transparent 'soft' phenomena like fur or clouds or similar that would ordinarily need to be rendered using possibly semi-transparent curves/sheathes (for fur/grass) or voxels for cloudy things like steam/mist. I gather splats can also represent and reproduce a limited amount of view-dependent specularity, as other commenters have said this is not dynamic and cannot easily deal with changing scene geometry or light sources.. still sounds like a fun research-project I make it do more in terms of illumination though!
