I love when these topics become border disputes. At the risk of being controversial, I'd have to say it is a matter of preference and nothing more. When all is said and done it is the same powder, with relative variance that is insignificant to the end result.
E scales are probably faster - the 8 minutes I save has no value to me. I enjoy the process, I'm not a factory. I can just TiVo the "Real Houswives" and skip the commercials.
Model T vs New Corvette analogy - maybe a little bit of an overstatement - only true if you are using either to puts to the end of the driveway to get your mail.
Now I often agree with Gary, but I struggle with this argument mightily. If PW or RR are using the same level of technology as is used in your Chargemaster, I would be pretty surprised. Not at all saying the Chargemaster isn't perfectly effective for reloading, I just don't see the parallel.
The argument is drinking a Coke through a straw vs drinking it from the can. History tells us you will get that refreshing Coke down either way. To each his own.
