My favorites so far are Mentos Pure Fresh, followed by Wrigley's Extra Professional Spearmint flavor. My least favorites are Mentos Full Fruit (too sweet!), and Wrigley's Doublemint Lemongrass flavor! You've heard (or read) it right... LEMONGRASS! Isn't lemongrass worst than mint?
Now I can buy more new flavors, because I have a friend to chew them with ^_^!
