I bought the first 3-hole turret press when it came out-traded a 22 rifle for it even up sometime in the early eighties. I started shooting USPSA around 1987 and have loaded hundreds of thousands of round on Lee turret presses 3 and four hole. Loading on the turret press, especially for new reloaders, you only do one thing at a time and you can watch each stage as it indexes to the next stage. The new reloader can watch all the stages of reloading from sizing, belling the case to dropping the powder charge, to bullet seating to crimping....Dillion make fine quality equipment but Lee makes reloading a little safer because you are not doing all the functions at one time.
