That would depend on the application like anything engineered. In
general the current type would be best for Hertzian antennas and I would
only use the voltage type on random/long wire Marconi type antennas.

What does this have to do with BALUNs?

A random wire is not a Marconi antenna. A Marconi antenna is a 1/4
wave vertical with a formal ground screen/radial system providing a
second 1/4 wave image below the earth which allows the system to load
like (but radiate like) a half-wave antenna. A Marconi antenna is ca.
36 Ohms and needs no 9:1 or 10:1 transformer.
