Forgive me if I don't use the right "lingo" - but I hate the omniscient POV. Peeking into every person's head - or worse, changing POVs briefly in the middle of a novel, like when we've been following Sally for 100 pages and then we hear Jane's thoughts for a paragraph or two - seems to call attention to the writer instead of making me feel immersed in the characters and story. The only time I think this sort of tactic kind of works is when there are clear delineations between each character's headspace - i.e., chapter 1 is Sally, chapter 2 is Jane, chapter 3 is Sally again, chapter 4 is Bob. However, I still find that this approach enlarges the psychic distance between the reader and the characters. Offhand, the only author I can think of that masters this technique is Stephen King, but his writing has the flaw of every character having the same voice. He's saved by the fact that the details of each characters life are so dense you REALLY get to know each one.
Personally, I prefer the first-person or third-person focused (again, not sure on the lingo, but I hope you know what I mean). I like to really get into a character's mind and heart.
It may be to your advantage to familiarize yourself with the terms. The bolded is not omniscient, it's third person limited with multiple viewpoints. And King is far from the only author to master this technique. Many authors surpass him in this.
Omniscient provides a single narrative voice that by definition
knows all, including character thoughts and feelings. It does not necessarily tell all.
Watership Down is a great example of omniscient POV done well. Many stories require a wider angle. There is no "worst" or "best" POV - only the POV that best suits a given story.
Third person limited keeps to one POV per scene, written in third person (he/she, him/her). This can be a very close viewpoint, every bit as close as first person, or even closer, in some cases. The advantage is that it allows the author to share information that the viewpoint character might not naturally say or write in first person. For example, if the character is an extremely private person, or deeply ashamed of certain things he's done, it may undercut the story's credibility to have him sharing his innermost thought in an I/me narrative. Who's he baring his soul to, and why?
First Person is narrated by I/me and is also a close viewpoint. Even in first person, the author is not limited to one viewpoint. As with third person, the POV can change at chapter breaks. The example I always give of this is Matthew Kneale's
English Passengers, which used 11 distinct first-person narratives to great effect. Another good example is Barbara Kingsolver's
The Poisonwood Bible, which if I remember correctly, used four distinct first-person narratives.
