All fields of astrology, Western, Chinese, and Vedic, are equally accurate. The only difference between these disciplines is the elements utilized by them and their origins. For example, Vedic astrologers factor in planets, nakshatras, and constellations in their predictions, whereas Western astrologers ignore these elements.
Hence, this is why I recommend that you get multiple readings from astrologers in different disciplines to expand your horizons. Sites like Kasamba feature gifted astrologers skilled in the fields of Western, Chinese, and Vedic astrology. And because of its introducotory offer, you can get a feel for these different fields without spending too much.
