Believe it or not, it's just like choosing between whether to use a Mac or PC. They both work and you can get the same results, however, more people use PC because it's more affordable and the software and accessories are more affordable, etc.I'm an astrologer but I have several friends who are psychics and/or tarot readers, runes readers, etc. When reading on certain events or individuals, more often than not we get the exact same results with some of us able to fill extra little blanks here and there.
My suggestion is that if you resonate with one type of system over another, go with your individual flow if it feels good and works for you, whatever gives you the most accuracy. I personally use the tropical zodiac but there are a few excellent vedic astrologers who frequent this site and that system automatically uses the Sidereal zodiac.
Good luck and welcome to site.
