Windows has become a complete piece of shit these days: almost nothing works well, there's ads built-in, security is just a big joke. I've taken to keeping my Windows machine for gaming only, network-isolated from Microsoft and re-imaged every 3-6 months.
My Samsung "TV" draws almost 40W of power when it's turned "off" - I have to physically cut the power to it. There's also no way to disable Bluetooth. Spyware seems to be the fait accompli for Samsung.
According to what objective measures? A 12 year old literally "hacked" the iPhone to remotely and silently activate any microphone using only a phone number. Apple products are not secure.
