Depends on how much you want to spend, though some low price units often hit well above their weight, it seems.
It also depends where you stand ethically - for example, Hikvision often makes great stuff, but they also literally built a camera with an AI built-in that identifies Uyghur people and triggers an alarm if it does.
The Hook Up does reviews heavily focused on image quality, and setup/installation, both physically and network/software wise. He often covers a wide range of price points instead of just focusing on cheap stuff or expensive stuff, and does image tests in daylight, nighttime, stationary, moving, license plate and person, etc. Even does edge-of-the-lens tests to find cameras that have crappy lenses.
The current 'hotness' would be low-light color cameras; sensors have gotten good enough that some ambient light will do, and the color helps with IDing people's clothing, and cars. Potentially license plates, too.

He's also done probably one of the most technically competent reviews of LED light bulbs I've seen in ages.
