Each avatar performs specific deeds. Rama killed Ravana, built the bridge etc. Krishna plays the flute, did the Kaliya dance and so forth.
Does scripture ever praise one avatar by citing the deeds of another?
Tulsi das transfers the praise that is due to Vamana (whose feet are said to release the Ganga from Satyaloka in some puranas ) to Rama.

From (se) which (jin) feet (caranan) emanated (nikalI) the river of gods (surasarI - ganga) and immersed (samAI) in the matted locks (jaTA) of Lord Shiva. Since then, she was named (nAm paDyO) jaTA ShankarI and she came (AyI) for the redemption (tAran) of the three worlds (tribhuvan).
