Comparing screenshot is useful. And there have been a lot of interesting posts these days with useful screenshots comparison.
But asking for an old algorithm to be included without screenshot comparison, I'm not sure it will motivate a dev to accept the request that easily.

As to "personal looking" in the end, I agree with you, but this has to be judged by people who know what to look. Non professional people will not judge the algorithm and are subject to placebo effect. And it is unsure they have done all good settings in the complicated chain of elements to do right !
Again, screenshots avoid endless discussion with nothing.

@others: good job at doing screenshots comparison ! (and also for not embedding big images and using links instead !)
