Digital if it's calibrated correctly.

Both are equally accurate if the acceleration of gravity is 9.81 m/s^2.
However, if there is a slight variation of the acceleration of gravity in a particular location due to the underlying geology, and this is a common situation, the digital scale cannot correct for it, whereas the beam scale will remain true no matter what. For that reason, the beam scale is slightly more accurate everywhere.

In theory, piezoelectric scales are the most accurate scales available to physicists, but in practice, such as bathroom scales, beam scales are more accurate and reliable. Manufacturers just aren't producing digital scales as accurate as they should be, in spite of all the ballyhoo. Bathroom spring scales should be outlawed for dissemination of gross misinformation.

A digital scale.

The one that costs more.
