Using reasonable price, availability, consistent quality with no surprises from year to year, box to box as the gold standard... the winner is....
Padron regular line. Rock solid in construction and blend, for the most part they are readily available and won't break the bank. Pretty much any size but if I was forced to pick: 2000 or Delicias maddies but I'd never turn down a natural either.
Olivas are in that class too.
