To you. A review can't (and arguably shouldn't) be everything to everyone. For example, for those who are flexible in the operating system they use, it would make more sense to compare with different manufacturer's products; for those who are interested in using macOS, it the review as written makes more sense. The first sentence of the piece is "I’ve been using Mac laptops for a long time, going back to the very first portable Apple ever made": it's unlikely they're writing to the former audience. You may not be the intended audience, and that's okay. There are likely reviews out there that address the questions that interest you. This just happens not to be one of them.
This is the exact comparison I want - to know in which ways it is different from what I have now.
I'm not going to switch away from MacOS on my daily use machine (though do have various ThinkPads with FreeBSD and so forth), so comparison to the hardware other manufacturers hardware produce is irrelevant to me.
the benchmarks also pretty much scale with cpu core count. I’d like to see some web, compilation, video and photoshop benchmarks, stuff people with Macs actually do.
Of course it's going to be faster. The problem with Mac is not that it's slow, it's the lack of innovation.
