Mike, what you're talking about is not "quality" but a certain look. The "look" is something like using a different film in your camera. When we browse through the MW beta images the look was really different than what we have in 1.1. Way back it was more blurry, different contrast and etc. That was the reason why Maxwell became so popular. When we look at new fry pics we see people using alot of non-post-prod sharpening which makes the pictures a bit synthetic-like because the sharpness brings out the artificiality of the models,textures,bumps. Also the noise pattern is not so good looking but that's an inevitable side-effect of the sampling scheme.
Maxwell Beta was really a king at making the synthetic models to look life-like. Sure you give it a certain sharpness, have nice looking photo-grain and you can even throw in a stronger chromatic-abberation. All these features will make it more life-like and therefore better looking. But when you sharpen it, give it enough time so the nice looking noise goes away then it's basicaly like using a flawless professional camera. You will start seeing the artificiality which was masked by the features of the renderer.
Such an unbiased path-tracer is something very interesting. Simply if your input data was perfect then your output data should be perfect too. Perfect materials and modeling makes perfect pictures. That's what the "unbiased" word is for
So the primary goal is to have as much "looks" as possible since variety is really the spice of life and different films suit different scenarios. The current maxwell is not good for every scene and such scenes could look better with fry's different looks (because it has more). Once both renderers have enough looks this issue won't be such an issue and again the focus will be more on the artist and what is he capable of. But still it's more like up to 70% on the artist how good will the picture be looking. We see insane pictures did with that "low quality" Vray and honestly they can exceed the look because it's so tweakable you can get virtually anything from it.
And features scotch taped???. That's BS talk. Like the thing with that drummer guy before.
Mike look, you're an author of not very wise statements so on this issue you are probably not reaching the the true wise "golden standard". You may be a pro, done this and that but still that doesn't mean you're always right. And in this case I take again my mini right to tell you that you're horribly wrong and you simply do it because of your own personal let's say "issues".
