In fact, the value 16 is said to be the worst hand one can have in blackjack. Since sixteen of the other fifty cards have a value of 10 and four have a value of 11, there is a strong chance of getting at least an 18 with either or both split cards. A hand totaling 18 or 19 is much stronger than having a 16.
In most cases, yes, blackjack offers the best odds in a casino. This is largely because there are three outcomes here: a win, a loss, and a tie (push). Since the odds of a push rest at 8.48% and the chances of losing come in at 49.10%, the probability of winning a game of blackjack is high at 42.22%.
