My laptop came with a Mediatek MT7921 Wi-Fi 6 chip, works fine with Wi-Fi 5 networks but is dogshit with Wi-Fi 6 networks (think <8Mbps download speed), to the point where the only solutions to it I see online are to disable its Wi-Fi 6 support via the driver and make it run only on Wi-Fi 5.
The final nail to the coffin for me is that the Linux driver for it doesn't support disabling Wi-Fi 6 specifically (so my only recourse there is to disable 5GHz entirely and fall back to 2.4GHz, and even that works better than it did out of the box), so I tossed out the stupid thing and replaced it with an Intel AX200, never looked back since then.
My laptop before this current one also had an Intel Wi-Fi chip, and it has worked flawlessly too.
So, as far as I'm concerned Intel is either the best or at least one of the contenders for the top spot, and Mediatek should definitely be nowhere near the top.
