i voted for all of them that i enjoy, but there's a few that i hate. our house used to be full of scent making candles and other devices, to the point i couldn't take it anymore. vanilla and fruit/berries are my faves. currently, there is a pear candle, and a mountain rain candle in the living room.
pine can smell ok as a candle, but if it's incense, it smells like christmas gone horribly wrong with the tree on fire.
i hate spice, especially cinnamon. it gives me a dry throat for some reason, and then i can smell it all day, even after i've left the house.
citrus smells too much like industrial cleaning fluid.
