I stopped caring about OS reviews after virtually every Yosemite (10.10.0) review failed to mention the drop in performance and battery life and the discoveryd and Wifi problems last year. These were not isolated issues and a lot of people suffered them, I'd say in a much higher proportion than any first release of OS X since 10.0. At least the Ars Technica people are smart and recommend people to wait until 10.11.1 if they can (although last year Yosemite 10.10.1 didn't solve anything).
I have to chuckle when I see some reviews saying "UPDATE _RIGHT NOW_! THIS IS THE BEST OS EVER!". They said the same last year, what a coincidence. Personally, I feel that Yosemite 10.10.5 is very stable now, and I'll wait at least until 10.11.2 to upgrade, no matter how many times people tell me how wonderful El Capitan is.
