Ars has always been consistently in-depth and technically insightful, somewhere in-between TechCrunch/The Verge and Phoronix/XDA Devs.
My only minor complaint is that Ron Amadeo is so transparently bitter about every little bit of Google news, to the point these days he only reports the bad and very rarely the good.
Like, the last news article on RCS was about 3 years ago... Right before all four US carriers standardized on Google Messages + Universal Profile (and three of them on Jibe). There's been a mountain of RCS developments happening lately but it doesn't fit the narrative of "Google is bad at messaging" so no articles are written. You can bet if RCS has even a minor gaffe, it'll get an article. (See this play out with Ars' reporting on Google's payments efforts.)
Other than that, Ars is my go-to as well. I just have to mentally apply the Amadeo Bias Filter before I read any article about Google.
For the record, I am also incredibly bitter about Google[1]. But I'm not a reporter.
