My father in law has one, and having used it, I'm not impressed, at least in terms of what I was trying to do. (I was loading 9mm with Unique.) I felt like I had to re-weigh every charge it trickled, and probably 1 in 5 would be off by several tenths, sometimes even more, which is a lot when your target charge is in the range of 5–6 grains. It seemed like when it would try to trickle out the last little bit of a charge, it would inevitably end up with a situation where a bunch of flakes of powder would clump together and then all fall at once. It was neither convenient nor efficient. Frankly, I don't understand how he puts up with it, as I know he uses it to load .38 spl with Unique, which has to be pretty similar.
The powder measure on my Hornady L-n-L press throws considerably more consistent charges. Maybe the RCBS works better with spherical and/or stick powders, or for larger charges like you'd use for rifle loads, but with small charges of medium to large flakes like Unique, it made for a large number of charges thrown back in the hopper, which slowed down the already non-speedy process of loading pistol rounds on a single stage press.
