Which wifi card is recommendable for Linux?

Hi,
I am currently about to change my wifi/bluetooth card, since mine which is the Realtek RTL8822CE 802.11ac is quite annoying in some aspects like that it seems to not support p2p which is needed for miracast. Also there where quite some unique problems with that card. And before I purchase a card, which has similar problems, I want to ask here, which cards which have both wifi and bluetooth, are recommendable. A link to Amazon or smth similar would be nice.

Pretty much anything Intel-based.

Here is an in-depth list of recommendations from a very knowledgeable wifi expert.

He is very big on Mediatek, however the Mediatek adapters are far from my favorite brand of adapters. They do have kernel support, however I feel their drivers are far inferior to Intel's offerings. However, Intel does not produce USB versions of their wifi adapter's.
