I suppose sidereal is more accurate ?
The setting is different for the tropical zodiac. The reason is, the Earth's tilt is already in use, locating the tropical Sign-boundaries. So, the tropical wheel rotates with the sidereal Age-indicator, and it always stays put at the 1st point of tropical Aries.
Instead of using Earth's tilt relative to the Sun, the tropical version utilizes the elliptical shape of Earth's orbit relative to the Sun. As in the sidereal case, Earth's wobble causes the transit, but it's Direct through the tropical zodiac, as opposed to the Retrograde movement of the sidereally placed Age-indicator. And, a tropical Age-degree generation is about 58 years, instead the sidereal 72 years.
Now I'm going to have to get on with starting the new Ages thread to fully explain the astronomy of the tropical version, along with what led to its discovery.
For now, I'll just say that it's currently at a median, or "Mean" location of 27 degrees 45 minutes of tropical Capricorn, Direct. So, this ongoing capoeira fight between Pluto and Saturn in late Cap has everything to do with the transition from the tropical Age of Capricorn into the tropical Age of Aquarius. Very crucial situation in the Age context.
The Retrograde sidereal Age of Pisces is far less crisis-ridden. The location of the sidereal Age-indicator in a sidereal zodiac is equivalent to the "ayanamsa", which is in early sidereal Pisces--but, exactly where is entirely dependent on how the individual siderealist sets the sidereal Sign-boundaries.
