The one true zero is just 0. No plusses, dashes, letters, spaces or any other superfluous fluff.
Ah, but this poll isn't about the one true "zero" but about the best "true zero" — of the various values in Perl which are zero in numeric context but true in boolean context, which do you like best?
Just "0" fails cos it's false, not true; you need some of that "superfluous fluff" to make it a "true zero".
