Which is better in reward: prayer upon the Prophet or tasbih and tahmid?

Both forms of remembrance are combined: Sending blessings upon the Prophet (peace be upon him) before and after supplication is recommended, as it is a cause for its acceptance. And the remembrance "Subhan Allah wa bihamdihi, Subhan Allah Al-Azim" (Glory be to Allah and with His praise, Glory be to Allah the Almighty) carries immense reward.
