Camo (https://reincubate.com/camo/) has been absolutely fantastic. I wanted to use my iPhone Xs when on calls and not have to fiddle with with plugging it in every time I needed a video, so I ended up using an old iPhone 6 and it still destroys every webcam. $40/year isn't the cheapest but it works so much better than EpocCam (which I had been using before).
I’d second this. Camo is fantastic and with an armature mounted above my monitor I can get a much more flattering angle with a great picture even on an old 6+ front facing camera.
Main thing real cameras are better at is bokeh, but you won’t get that in a webcam. And software can passably fake it these days.
