To give the short answer, higher voltage is better than higher current,
due to lower losses in the typical case.  Usually it's not a huge
performance difference though.

If a very high voltage of 100kV or so is used however, corona losses,
insulation problems and/or gap problems may negate the advantage
of higher voltages.  For this reason, folks usually use a voltage
between 10kV and 40kV, but many people have built fine coils
that run at lower voltages.
