How is Vedic Astrology better than Tropical Astrology?

Sometimes I feel Western Astrology isn’t just me. I’ll read my chart and find that some of it fits me than some of it doesn’t.

And does Vedic Astrology center only on the ascendant, and if it does why? In Western Astrology, I know for a fact that the Sun, Moon, and Ascendant are all equally taken into consideration. Why not in Vedic Astrology?

I like Vedic Astrology and I want to know which one is better and more precise. Does Vedic Astrology also include synastry? It’s really bugging me, and I just need to know.

Thanks in advance! =]
Also how long has Vedic Astrology been around and why isn’t it as or more popular than Western Astrology? I’m beginning to think Western Astrology is weird because of what I’ve read about Vedic astrology.
