The final speeds are identical.

Work Step by Step

For the balloons, because we are told to ignore air resistance, their initial energy (kinetic plus potential) equals their final energy (all kinetic). They start at the same speed and have identical initial KE, and start at the same height, so they have identical initial gravitational potential energy. The final speeds are all the same.
