Nope, blackjack has the better odds for you. The odds in favor of the house are lower than hold'em.
Now, concerning competition, (like tourney,) then yes; hold'em is the game you want to play.
In BJ, if you play basic strategy and follow the rule of money management, you can come out on top against the high rollers who either bust or beat by the dealers hands. A+10,J,Q,and/or K cards...aka 'Blackjacks' are rare. Unless you actually have done mathematics against the decks, then the odds are in your favor. Even if you are in super saiyan mode, the house will always have the advantage in the long run...regardless of the game!
