I use both, sort of. I write from a third-person perspective, but the narration is that of the character; for instance if the character is drunk, groggy, or drugged, sentences will be short and sometimes open-ended. (Example: Light. A blur of colors, muted sounds. His own breathing. In. Out. Slowly, regulated, like waves in a sea of life. His side; pain. Light, blinding this time. No. Too soon. Light was bad. He had been blind. Altos could not think. Sedatives. Of course. He was drugged. What did they do to me? He had been out too long. Why am I here? What is this place? What happened to me? His mind was a blaze of questions. He could barely remember the events of yesterday. The day before? No. He couldn’t think; not good. ) Sometimes I "zoom out" to provide a bigger view, but as a general rule I write from third-person omnipotent (third-person with the ability to look into the minds of characters)
