Honestly - Pretty much every laptop Apple released from 2018 to 2021 was a complete turd.
I have the 16 inch 2019 model (issued by work, I don't buy apple products) and it's... just not a good machine.
It gets amazingly hot, the fans run ALL the time, the usb-c ports are flakey at best (frequently stop working after a suspend/resume cycle, or if you unplug while the machine is closed).
It's got a shitty touch bar instead of function keys (although at least it reverted to a real esc-key, the touchbar only esc was literally a joke).
It has frequent rendering glitches and artifacts.
The battery life is bad (basically a given for how much power this thing is dumping right into my lap as heat).

Before the M line, I was about to go have a real fight with our IT department to get me issued literally anything other than another Mac. The last couple of models they've put out in the intel line are just genuinely bad machines, across both the pro and air lines.
I spent months complaining to them about this laptop. I had an Air for 5 years(!) before this and it was a wonderful machine. For 2k I'd expected a decent machine - but I hate everything about it. Obviously Apple didn't care in the slightest.
