Reviews and comparison magazines/sites have been a scam for decades, it's not anything new.
USwitch literally only considers a small handful of things for me, and when I run off and do my own switch, things work better and I get far more options.
Same for car insurance, I can play a dozen comparison sites off against each other and many big-names only appear on a small handful of sites, and their deals are often not significantly better at all.
Same when you used to go into Dixons/Currys and look at their fridges and realise that it was a model number they had basically made up for an existing product, rebranded, and then sold in stores only to stop you "comparing" it because nobody else could sell that model number.
My distrust in all these things means that I rarely, if ever, use them and if I do I only ever use them to exploit their lowest deals entirely (because they do the old bait-and-switch on you to give you a good introductory deal which they later do not offer to any existing customers ever again, only new customers).
It's all a scam, and nothing much has changed in decades.
I know someone who would only ever buy whatever Which? magazine recommended, in all kinds of areas. Turns out they always ended up buying a load of overpriced old shite. I always just found it hilarious - I've worked in IT for nearly 30 years and they would ask me my advice, I'd steer them towards exactly what they needed, told them why "their" (Which?'s) choice was junk, and they would then just buy whatever Which? recommended, which was always junk, and then they'd try to complain to me and make me do support for it. Nope.
I now don't trust any comparison, professional review, or site that claims to be impartial. The only thing I can do is look up the product specs, demo it for myself, and try to cherry-pick through the mass-aggregate reviews of 10,000 or more users and try to find the one review that does raise items of concern to me. I literally can't trust anything positive, all I can do is hunt for the stuff that makes me suspicious, like a pessimistic old crone, and then see if they were right. You mean that NAS does fail a lot and the restore process is a pain in the butt? Yeah, that's what I want to know. Not that it got 5 stars against the same manufacturer's previous model's 4-and-a-half stars.
