I use scales a lot and have both, a couple of electronics and a 10-10. To be honest I use the 10-10 about 10 times more than the electronics. It is always sitting there ready for use. If you do not move it the zero stays constant.
The electronics are faster and easier to use, not sure if they are significantly more accurate. They do have to be zero'd a lot, more than I like. They are also sensitive to moving air, like near a heating vent or air conditioner outlet. I like the elecrtonics for weighing bullets, bigger jobs like that.
I have the system with the infra-red beam or whatever that talks between the scale and the trickler and also a powder dispenser. Fancy stuff, but I almost always use standard powder measures and the good old 10-10.
One suggestion, if you use RCBS get the micrometer adjusting stem for the powder measure, really works nicely and is repeatable (other brands have micrometers also). I have a measure and press on one bench and the 10-10 on another so that the scale doesn't get effected by movement.
