This is one of those questions that involves alot of personal preference. They both have their good and bad. One of the things I really like about my digital scales is how fast it is. Especially for weight sorting brass or bullets but how fast it is is also one of the things I hate about it. They can be sooooo sensative to the slightest air movement that the readout changes or can change very rapidly. That's why you see so many have the little enclosure, to help eliminate air movement. Those little load cells are really sensative probably because they are weighing such light weights.
I have 3 scales total. A Dillion digital, RCBS Chargemaster and Redding beam scale. You will probably find this to be odd but the Redding beam scale is the scale I use the least but if I could only have one scale it would be the Redding beam scale.
If you ever do get a digital scale either leave it turned on all the time or give it ample time to warm up before you start using it. The load cell needs time to warm up or they give false readings. I've also read fluorescent lights in your loading room will throw them off too but I have no proof of that.
