UBI is far easier to understand. It's exactly what we have now (with perhaps higher taxes), except you get a cheque for $Xk as well. NIT is a counter-intuitive trick to achieve the same thing within a tax bracket framework. Maybe it's more elegant, but understanding it requires a comprehension of mathematical concepts that many people (especially on lower incomes) simply don't have.
