It is not possible to determine the best zodiac sign as it is a subjective matter and varies from person to person. Different sources rank zodiac signs based on different criteria, such as qualities, popularity, positive and negative traits, and dating compatibility. For example, one source ranks Capricorn as the best zodiac sign by qualities, while another source ranks Cancer as the best zodiac sign to date. However, it is important to note that these rankings are not based on scientific evidence and should be taken with a grain of salt. Ultimately, the best zodiac sign is the one that resonates with you and helps you understand yourself and others better.
