Data-filled indeed. Pages of benchmark results, most of them for some obscure web benchmark (WebXPRT). The results show in so many ways that an i5 tablet is much faster than all those ARM tablets. I learned very little from that review that was not also covered in other less technical reviews. Basically Anandtech is throwing softballs at the companies that the site depends on to a large degree. I can understand that, but they do not exactly deserve praise for it.
As for the Ars review, I found it excellent. The extensive coverage of the display scaling issues was the first time I ever read a comprehensive explanation of how this is handled in Windows. Very informative!
