I'm sorry to hear the Pistachio flavor didn't work out for you. Flavor preferences can vary widely, and what might be too much for one person could be just right for another. Since the Pistachio wasn't to your liking, perhaps you might enjoy something with a softer, more traditional flavor profile. The Vanilla or Banana Shake flavors are generally well-received for their more classic and less pronounced taste. If you're looking for something different but still want to stay within the shakes, these could be great options to consider.
