I love switching in first person POV, but I will say it took me a long time to figure out how to do it in a way that felt right to me. Admittedly, I do start off by putting the name at the top, but then I try to make sure the personality of the character shines through. Typically, I like to have at least 2 characters that I switch between and every now and again I will sprinkle in another person. Kind of like when a show reveals something but only the audience knows. And whenever I have any scene overlaps it usually reveals something that wasn't revealed to the main character or shows the emotion of the opposite character in the scene. I don't do that too often because it does feel a tad repetitive when it's overdone.
I have written in third person, but just couldn't quite get the feel I was looking for. I can see how third person omniscient can benefit storytelling, it's just not the style that draws me personally. Like, I don't mind reading it, but writing it is just not my go-to.
