St Barts is a very nice tropical scent. Tequila and lime mostly with a little coconut. But, very poor longevity, and not so versatile. Haven't tried Marc Jacobs, so i can't comment there. But, if you have the money and want an excellent fig scent, I must recommend Philisykos by Diptyque. It is like heaven for the fig lover.
BTW, you smelled your name wrong.
