I have both.
One I use daily, Astrologically Inclined. With the audio added, definitely felt the energetic effects better. Feel more at ease, crazy eclipse and oppositions? Nah.
The other weekly (I know it has longer lasting effects) just that if I feel some challenging aspects happening with celestial transits.
To my understanding, Navagraha Homam is an actual powerful ritual devoted to the nine planets to gratify them.
Using both, I feel personally, the current natal phase albeit challenging, it is smoother.
Helps with rahu/ketu. Remedy to block unfortunate events.
There are good days and bad days, but mostly I feel success.
