I kind of think you need both and electronic scale and a mechanical scale. One thing I noticed about my 1010 is that the movement of the beam as you added individual granules of powder was smooth and consistent. I literally could be seen to move when adding one granule of 4895 at a time. That is pretty sensitive.
The Electronic scale can be as much as .05gr - or .05 gr + and still read the same number, then when it clicks over to the next number it can be the same amount off. Really this doesn't amount to anything in loading ammo, but the mechanical scales are more accurate if you want to split hairs.
You can quickly check one against the other too which is reassuring.
