Depends. I tend to like third person, and tend to write it... lately I've been trying to write 1st as well. It really all depends on what sort of story you're going to write- whether it will benefit from 1st or 3rd. as a rule, 3rd person you can get a full range of characters and descriptions, but it isn't as 'personal'. 1st tends to be very one-sided, unless you switch into different characters heads per chapter... even then, you can have an unreliable narrator, which isn't bad because it can provide the story with interesting twists and reveal more about the character themselves.
