Don't exist "best build" you create your char in the way that you like. Personaly i dislike of Hybrid builds cause you waste the potential of your character (when i say hybrid, understand that like skills ok? Not stats).
Mine is 1144 gunner. Was a pain in the ass for level but my effort was rewarded in the end. If my life isn't easy with 4 of charm i cannot imaginate someone with 1 of charm.
