Following is a response from DHS Lead Statistician, Ruilin Ren:

DEFF vs DEFT is like variance vs standard error, there is no preference. As DEFF is often used for sample size calculation, DEFT is more convenient for confidence interval calculation. Since DHS reports standard error and confidence interval for key DHS indicators, so we report DEFT instead of DEFF for convenience.
