As part of our statutory duties, we have to report on all elections.
We do many things to get information. We do public opinion surveys, and we ask the question, “Did you find it easy to vote in the polling place or via postal vote?” We regularly get in the low 90% saying that it's easy to vote and expressing their preference, easily, for all four electoral systems.
We haven't actually ever asked which electoral system they prefer. However, they do find all four easy enough to fill in, if you think of it in terms of completing a ballot paper.
