The extended version of bija mantras are more powerful when working to empower the chakras. This is from experience and experimentation.
Base Chakra: SHANISWARA, vibrated as SH-figure of the past-NEE-Zevism-VAH-RR-figure of the past
Sacral Chakra: BHAUMAYA, vibrated as BB-AHH-UUU-MM-figure of the past-YAH
Solar Plexus '666' Chakra: SURYAE, vibrated as SUUU-RR-YAH-YAY
Heart Chakra: SHUKRAYA, vibrated as SHH-UUU-KKK-RR-figure of the past-YAH
Throat Chakra: BUDHAAYA, vibrated as BUU-DD-HAH-figure of the past-YAH
Sixth Chakra: CHANDRAMASE, vibrated as CH-figure of the past-NN-D-RR-figure of the past-MM-AHSAY
Seventh Chakra: GURUAVE, vibrated as GG-UUU-RR-UUU- figure of the past-VAY

For a formal working, like attracting money or love, you can use the extended versions of the planetary bija mantra.
Eg:
Aum SURYAYE Namah
Aum SHUKRAYA Namah
A great many people overlook what HPs Pythia said regarding planetary squares and their mantras after raising your energies:
Vibrating the word alone SUUU-RR-YAH-YAY, nine times, or a multiple of nine is effective. You do not need to vibrate all of the Sun mantra given in the squares. Following this, you may want to state an affirmation, directing the energy into a specific goal, several times.

What is the difference and purpose? Both mantra-wise and name-wise. I have read somewhere Surya is Azazel.
