Imagine a world where every product category had someone dedicated enough to build a site like this and keep it up to date. I'd specifically love one for cameras, lenses, and for the analog shooters out there, film.
Affiliate programs have destroyed this kind of web and Google happily suggests these sites as search results.
It honestly just makes me sad.
One solution is things like Consumer Reports and Wirecutter, where you have an institution that does some quality control. But I wonder if there's something in the middle, like a few good reviewers clubbing together and certifying one another, such that there's a recognizable brand that they share, one with meaningfully high standards.
He is not the "Stereophile" type of reviewer, for example.
However, there are certainly sites, and perhaps this is one, where there is considerable credibility (actual interest and knowledge), research and effort that I have no problem with the owner being compensated for providing the resource.
Even if just providing a more intuitive and deeper method to narrow down options to fit a narrower use case (which vac has the longest cord!), then there is added value.
The problem is discoverability. Though there are more sites like this than ever before, it's hard to find any of them. Google has been thoroughly conquered by content marketing at this point -- if you search for any product category, the first dozens of pages are 100% long form commercial advertising now. They all have much larger budgets and way better SEO skills than the average aficionado.
