Most astrologers these days use the Placidus House system. I use the Equal House System. I am slowly becoming familiar with the Placidus System, though I still feel it needlessly complicates a chart. I am also resistent to adding Chiron to charts. There's already enough going on with the planets so I feel like there's no reason to complicate things with asteroids.
(note: I still have a lot to learn about astrology so I reserve the right to change my mind repeatedly.)
