I prefer the Alekhine version. 1. e4 e5 2. d4 ed4 3. c3 dc3 4. Bc4 cb2 5. Bb2 d5 6. Bd5 Nf6 7. Bf7+ Kf7 8. Qd8 Bb4+ You give back the material, and this line is equal. I prefer to play black because of the queen side majority.
I have never lost to the danish gambit. After accepting the gambit I play Bb4+ and then Qe7 to protect f7. Usually my opponents resign after I capture almost all his/her pieces although I mated my opponent in at least one game. One of my best rated victories was against the danish gambit.
