I personally think it’s better using the Equal house system for calculating charts, and this is an advice that I indicate especially to those that are new to astrology.
I’ll put it simple: If you’re born in Oslo, you will have probably more interceptions than someone who is born on the Equator with the classic/Placidus system. And to me this concept of astrological imbalance doesn’t sound good.
The placidus system was calculated wrongly for a lot of centuries, during in which it became a standard system for the Western Astrology. People that are born on the equator have less energetic imbalance in the chart than the people born in Alaska or in South Africa? It’s not right. So after some researches I found that the equal house system is better, especially for interpreting chart, understanding conjunctions and the meaning of the houses.
With the equal houses the only thing that changes in most of the charts is the placements of the planets, so If it happens that someone has a stellium between the 7th and the 8th house it could be that with this system he/she can see clearly if his or her stellium is in the 7th or in the 8th rather than between the two. Another thing that changes with the equal houses is that we have MC on the cusp of the 9th house, the house of the “philosophical enlightenment/experiences” and to me, the MC fits perfectly this house because it represents who we truly want to be, our aspirations and secret desires, unlike our ambitions, that are represented by the 10th house.
