There are a few different chemical formulations that various brands have used over the years and for me Jungle Juice Platinum was always better. Less offensive off-odors, clean almost like a wine-based distilled alcohol character. But whatever brand you get, keep them in the freezer to keep them from going off quickly after opening. You can get 6 months or more if you keep them in the freezer; at room temp they'll start to smell like ass after a few weeks.
