I use Podium V2 all the time and in terms so speed, ease of use and output quality I think it leads the field. I have a license for Shaderlight and have put quite a bit of time into trying it, but it seems for interior renders, which is primarily what I do, it is very hard to get rid of the noise in the render without taking out a ceiling or walls. I am sure it is doable, but it has not proved easy or intuitive.
The improvements in v2 vs v1 are signifiant, far fewer artifacts and hotspots, bump maps are easy to apply, you have spotlights, point lights, and light emitting materials to work with. I have gotten so I can light, adjust textures and render a good quality render in about 3 hours.
