Speculating here, but I think it's probably due to the difference in how thoroughly the planet was destroyed in each case.

All that was clear about the laser the General tanked is that it would destroy the Earth, which does require around 60 zettatons (60 sextillion tons) of TNT at minimum, since that's Earth's gravitational binding energy.

On the other hand, in the manga panel that DB showed, Kirby destroyed Popstar so thoroughly that there was nothing left of it, which would require much more energy than simply overcoming the planet's GBE. That's probably the reason for the difference in numbers.
