Hennessy vs Remy Martin vs Courvoisier vs Martell?

Going to buy a bottle of cognac but can't decide which one. Never had cognac before, planning on drinking it straight/ mixing it with Hpnotiq to make Incredible Hulks. Which one would you suggest? Only buying the VS version to start with because I don't know if it will be a consistent drink I stick with. Please only state one of the four above mentioned cognacs do not list some no-name brand simply because it is twice as good at half the price. Also any reasons for picking the cognac would be appreciated; as well as what to try after the VS if I decide I like cognac. Thanks guys! :D|||maybe martell
