I've tried every flavor except banana (just can't bring myself to order one for some reason- maybe next month) and I like them all. Vanilla is the best because of the simple taste. Strawberry has the best "flavor". Chocolate tastes the most like a dessert, so maybe it's the sweeter taste you don't like. Orange is just good.
The problem I have is mixing them with anything. No matter what I put in there, fruit, oatmeal, etc. I can't taste anything but the Metabolic Drive. The flavors are just that strong. My suggestion is not to waste the food with mixing and just have your shake (always with water- save the milk for drinking) and then enjoy the food separately. If you going to have the cals anyway, why not actually taste the food.
Surge is good, but it certainly is an acquired taste. I usually put in a little more water than it asks for, just to thin it out. The thing I hate the most about Surge is the vile foam that occurs when you shake it. Surge tastes good, but the foam has a horrible taste.
