Why you might not resonate with a big three (SUN, MOON, RISING) and why it might be more influential
-You might have more aspects with one more than the other
-a placement is in the planet that it rules (cancer moon, leo sun, aries rising)
-it is placed in a cardinal house

-there may be planets aspecting the ascendant or planets in the 1st house
-planets in the second house
-your big three might be Conjunct with another planet
-your big three might be conjunct or aspecting a planet that it rules (Capricron conjunct saturn, libra Conjunct venus)

-your big three might be Conjunct an outer planet
-your big three might have more negative/positive aspects than the other
-your big three might be aspecting a planet in the 12th house and or one of your big three is IN the 12th house

-your big three might be in a debilitated/at fall sign or it might be exalted.
-your big three might be opposing multiple planets
-your birth data is wrong or inaccurate
-you might have the wrong idea or understanding of a nakshatra placements/zodiac signs in general

-you might be a more masculine/feminine inclined person. Those who are more feminine inclined might resonate more with their moon. Those who are masculine inclined might resonate with their sun

-you might have a stronger elemental dominance in your overall chart. Say that your big three is all air, or mostly of the same mode or element, but the rest of your chart is earth, that might switch things up.

-you were born during a solar or lunar eclipse, full moon,or new
moon
-the chart ruler might be in a cardinal house or Conjunct the big three. (Say your sag rising, and jupiter is in a cardinal house or Conjunct moon or sun)

-you have multiple nakshatras of the same lord ruler in your big three(Punarvasu moon, vishaka sun, purva Bhadrapada rising, all jupiter ruled)

-I have most of my aspects with the moon and its placed in the 4H. However I barely resonate with it when it comes to my personality and appearance. The only way i relate to it is through how i deal with my emotions and what i do when im upset

I resonate with my Sun and Ascendant the most despite of what the moon is defined as (the mind, personality, sensorium)

Anyway i hope this helps!
