All of TVs liquids have an extremely strong taste compared to what I WAS vaping. The Cafe Machiatto is no exception. However, I personally find it to have a much milder flavor than some of the others (Atomic Fireball) and for good reason! What has a stronger taste, coffee with creamer or Big Red chewing gum? Certain flavors are used in breath mints because of their EXTREME flavor, mint and cinnamon are two of the most common. Therefore, it would make sense that these flavors are the strongest.
Cafe Mach has a "complex" flavor with many subtleties, similar to Blueberry Cheesecake, German Chocolate Cake and Bananas Foster (similar in complexity, not in taste!). In all of these liquids, you can taste the individual components which give it a lot of depth. So it really depends on what you consider flavorful... Intensity or depth?
My perfect middle ground at the moment is Bananas Foster. It is incredibly complex, tastes just like fresh bananas (not Laffy Taffy!) and carmelized rum with a distinct cinnamon taste on exhale. The flavor is very strong, but not overwhelming (like AF can be!) and the complexity is great (can taste each component individually), which keeps it exciting all day! Just my .02 =)
