How is that a bad faith argument? The PS5 Controller is not entry level quality. It's not my problem equivalent PC peripherals are expensive. My Razer Viper Wireless cost $150 and the build quality is just slightly worse than a Dual Sense. It's built to be lighter weight so that's understandable. But it's twice the cost, and that doesn't include a keyboard. I tried the G305 and didn't care for the build quality personally. Equivalent wireless keyboards with the quality control of Sony are $80-$100 too. I'd probably cheap out on the keyboard before the mouse, but every keyboard I've used under $85 had Quality control issues from switches stop functioning to buggy software (Anne Pro II), and Wireless was terrible on all of them.
I've heard issues dealing with multiplayer and anti-cheat as recently as this summer, so it's nice to see it's better, but until games are officially supported with no third party patches or workarounds, I don't count it.
PS5 is FreeBSD based, so yes it's Unix-like. But that doesn't mean anything. MacOS is also Unix-Like and it's terrible for gaming. It all comes down to support. At the end of the day I don't want to have to deal with drivers, or configurations to play a game. I want to press a button, and start gaming. For me personally Consoles are going to win that war 95% of the time. But I'm dumb. I spent almost 3 times the cost of a PS5 on a Graphics card last year for some reason.
