The Dillon and others are doubtless superior, but the cost is high.
I have used the old CH tool and do not care for it, though it works. I keep bending the rims when I get too exuberant.
I often hear folks who do not like the RCBS tool, but I find it easy to use and fast enough for me. As mentioned, the stripper must fit on your press squarely for any kind of success.
For a few dozen cases a pocket knife works better for me than a case mouth beveling tool. Early pocket crimp hand reamers would often create oval holes. Later ones do not do this. My pocket knife is quicker though.
The case mouth beveling tool creates those huge craters you see on many cases when I become bored with the tedium and tired from the gripping and twisting. It is too hungry for real finesse.
