Dispersion hardened alloy will have high creep resistance than the precipitation hardened alloy becaus at higher temperature precipitate dissolve into the matrix. But dispersed particle will not disslove and give higher creep resistance

See lessCreep is nothing but high temperature plastic deformation which mostly involves grain boundary sliding. Dispersion strengthened materials will have high creep resistance since the oxide particles doesn't dissolve in the matrix and pin down the migrating grain boundaries at high temp.

Precipitation Hardening is the most effecient method to increase strength of high temperature alloys i.e. for creep. Precipitation hardening is a strengthening mechanism very common in many classes of metallic materials, from Al and Cu allos to high strength steels. In special, precipitation hardening (PH) stainless steels may allow corrosion resistance and mechanical strength desired to special applications.
