Being an op-ed writer (with a healthy ego), I always write in the first person.
Depends on the story I am telling. I'm not partial to either one.
Depends on the story.
I like third person because it gives me the freedom to be flexible. With first person, the reader only sees the world through one character's eyes.
Probably first, noting that I am a travel writer (and a photographer - there is no section in your questions for one who does both).
I have always been really comfortable in 1st person. It makes me feel I'm closer to the bone!
Third person. First person seems jarring to me. Especially in romance. For me, the only author who's successfully written first person and have it be engrossing and entertaining is Jim Butcher, who writes the Dresden Files.
Totally third person. I get my thoughts clearer and I can write the images clearer when I write this way. It just makes me more comfortable in my writing.
I had originally written THE LION DOMINION in the 1st Person, as I thought that would work for a story that is constrained in time and space, actually taking place in a 5-day period set on a 150-mile long island. But, with the diverse characters, the several flashbacks and the sweep of the story, it just got too cumbersome trying to make sure that each character had a way to be aware of what he had to know to move the plot forward.
I finally caved in and changed the Point Of View (POV) to 3rd Person and life became much easier. My two other fiction works in process are similarly in 3rd Person.
However, another of my current projects (75% complete) is MEMOIRS OF AN AMNESIAC, a series of remembrances of friends and acquaintances (such as Robert Preston, Jack Lemmon, George C. Scott, Charles Nelson Reilly, Jason Robards, etc.) wherein the POV is, by definition, 1st Person.
I prefer first person, because it presents a point of view, interpretations and the feelings come through naturally. Not so when I write in third person.
Oddly, I prefer reading third person but writing in first.
I normally prefer first person story telling
