Here is my take on reloading equipment makers:
LEE- Low cost, medium quality, decent performance. They save money mostly by using simple solutions to problems, though it helps that all their stuff is built to a "just good enough" type standard. The best value in reloading equipment, THE place to start if you are not sure what direction you want to take in reloading. I run a lot of their stuff, but am planning a major upgrade soon (after almost 20 years as an on-again, off-again reloader).
RCBS- High cost, high quality, decent performance. This company puts the absoute best in materials and craftmanship into products that were conceived and designed by a bunch of drunks. Who the hell designs a priming tool that requires 100% disassembly to change the shell holder? Why does the Uniflow lock nut butt up against the cylinder retaining screw, so that you never know which will loosen when you try to adjust powder charges? Why does even the smallest adjustment to their dies require tools? All the cost of RCBS goes into overbuilding a poorly thought out product, and the value factor is, to me, the lowest on the market.
LYMAN- Who?
Seriously, I have one friend that setup with Lyman gear as a teenager, he has now mostly converted to Lee. Nobody ever discusses their stuff online, and I rarely hear the name outside casting circles. I don't know how they stay in business.
HORNADY- Kind of similar to Lyman, though the new LNL system has people interested again, and their dies are popular. Regarding their dies, I like them when they work, but of the four sets I own two have had to go back for warrantee work. Customer service has been very good. I think they have to work hard to keep us noticing them, as they sell middle of the road stuff, while Lee, RCBS and Dillon grab our attention with their category-defining products (though they may be defining the worst category, see RCBS above).
DILLON- High cost, high quality, high performance. These are the go-fast tools for those who know what they want, and performance is everything.
