I hear you, but you really have to use them to appreciate what a convenience they are. I'm not sure about instant gratification, but I really like improved designs. These things just make swapping out calibers a snap.
It's kind of like comparing the old car radio that just has a tuning dial, to one that has station pre-set buttons. Only takes a few seconds to spin up the dial to another station number (your die with lock ring method) each time you want to change the channel, but the pre-set buttons are a much better way to do it. With a 5 station progressive press and 10 calibers that I reload, I couldn't go back to the old way; no way. If someone is doing just a couple of calibers with a three die set up, or something, I could maybe see the reluctance; but even then...
I recommend you try them, I bet you'd be convinced!
