Subjective. As far as I am concerned, Apple maintains some of the best quality products available on the market. In the 30 years I have been using Apple's products, I have had 1 product issue that I had to go to the Genius Bar for, and that was a bad battery in my iPhone 5. They replaced the iPhone which was out of warranty with no questions asked. Stellar quality and customer service if you ask me.
The hardware experience has been excellent for me. Only unexpected issue I've ever had was an iPhone 6S battery go bad THREE TIMES, being replaced under warranty each time. That said...
You haven't experienced the memory leaks, app crashes, missing sidebar items, windows that vanish after maximizing, inconsistent and unreliable iCloud syncing, random Launchpad layout resetting, preferences not saving, Quick Look failing to load, file save/load dialog not remembering where it was, gestures deciding not to work, Bluetooth connection problems, Wifi passwords resetting, constant waking from sleep and draining the battery, share and export functions vanishing from the menus, etc etc etc in macOS?
Or maybe the lock screen freezing, apps instantly reloading due to terrible RAM management, background process runaways, keyboard not appearing or getting stuck on the screen, shortcuts failing for no reason whatsoever, AirPods dropping or only connection on one side, UI elements appearing halfway off the screen, battery draining for no reason whatsoever, music files not copying properly, Files app not copy/pasting properly, notifications not appearing, etc etc etc in iOS/iPadOS?
These and many more bug all appear consistently on my devices, work devices, friends/family devices, whether new hardware, older hardware, fresh install, or update. It ain't just an isolated case here and there.
The more lights Apple puts on the tree, the more bulbs burn out.
They are, objectively, getting sloppier with every release. There's a reason I'm holding on to my classic Mac Pro with Mojave until it will no longer function, and it's not because I enjoy paying the power bill.
Don't even get me started on their blatant and deliberate hardware designs that prevent me from fixing things myself.
EDIT: Forgot to add the experience I've repeatedly had with multiple Apple TVs where it won't sign in, then when it does, won't download the apps and just sits there spinning. Also randomly decides not to appear in my AirPlay or Casting options. My $40 Roku has been utterly flawless and does exactly what I ask every time.
