The color differences are from different "tone mapping" implementations after the render is stopped and can be ignored.
The point of that page is to evaluate renderer correctness (think of them as visual unit tests), not to really compare "which one looks better". For example, some of the images show appleseed with hard shadows, when they should be soft.
If you want to know which one is "right", Mitsuba is the one to look at as it's generally the most correct.
The graininess comes from not letting the machine renderer longer—the longer it goes, the less grainy it will be. That said, all of these renderers employ "tricks" to reduce the graininess that can make it practically impossible to remove whatever graininess slips through.
- horse3d 10y agoYou can't say any of these is "more correct" from looking at the renders. Those hard shadows stem from a difference in light size, which is almost certainly a problem with the scene parameters being treated differently. The light size may have been "lost in translation", turned to 0, creating a perfectly sharp shadow.
- franzb 10y agoOne limitation of appleseed today is that our physically-based sun model is a purely directional light, not a far away disk with a finite radius. This explains the hard shadows on some of the scenes.
