I guess it depends on what you want to achieve (stills from video is "faster" I guess, but not as good).
I pretty much only use my drone for photography (no video), and I always take photos. Some reasons are:
- To be able to focus on the photo and set up my composition. My kind of images (landscapes) are not well suited for "run and gun" photography. I like to take my time and compose the image just the way I want it.
- To get raw (DNG) files. I always post-process my images, and I want all the information I can get.
- To get the full sensor resolution. 4k video is always 16:9 and about 8MP resolution. I like the 4:3 ratio and the 12MP of the full sensor.
- To be able to merge several shots into one (bracket for more dynamic range, or panorama for more resolution/larger field of view)
It all depends on what you are trying to accomplish I guess. If I wanted a still image of a moving motorcycle that my drone is following or something, then I might consider grabbing stills from 4k video.
But my images are generally more like this one from a few days ago:
