I don't have a favorite hand, because in poker it's possible to win or lose with any hand, including premium hands.
In every possible texas holden hand, you can win and lose. There is never a hand that gives you absolute certainty that you will win preflop. Now the question is statistics, you can win and win with anyone, although you start a preflop win but you can still lose everything on the flop, turn and river. In show donw it is possible to win up to 10 - 2.
