I think you mean Pu-239, but we'll look at both Pu-239 and Pu-238

We'll compare to aspects, the decay energy and the fissile energy.

First the decay energy.

U235 alpha decays and releases 4.679 MeV in the process

Pu238 alpha decays and releases 5.593 MeV

Pu239 alpha decays and releases 5.245 MeV

For the fissile energy.

U235 fissiling releases 202.5 MeV

Pu238 does not sustain a fissile, but the spontaneous fissile is 204.66 MeV

Pu239 fissilings releases 207.1 MeV

Pu238, because it does not sustain a fissile (though it does go through spontaneuos fissile) and because it does not emit much other stuff, other then the alpha particle, it works great as a nuclear battery.

For example 8 oz of Pu238 will power the average laptop for about 29 years, without ever needing to be recharged or replaced.
