Daylight combines sunlight and skylight. The sunlight component can be either an IES Sun light, or a standard light (a target direct light). The sky component can be either an IES Sky light or a Skylight.
The IES Sun and IES Sky lights are photometric lights. It is appropriate to use them if you are creating a rendering that uses radiosity with exposure control.
The Standard light(sunlight) and Skylight are not photometric. It is appropriate to use them if your scene uses standard lighting (Sunlight with its Directional light works for this, too), or if you are using light tracing.
