My turn
I used a Lee Turret for three or four years for .45ACP, .45LC and .38Spcl. It's a very simple system that allows changing calibers very very easily. Get a turret, powder charger and dies for each caliber and you're in business with 2 minute swaps. It never broke. The dies are easy to adjust, and the powder charger is consistent. I never found that the chart provided with the discs was as close as I'd hoped, but you weigh everything to be sure, right? The biggest drawback I ever found was speed, but it still beats the heck out of a single stage set-up. Once you get at routine down it goes easily and fairly quickly. I could make 100 rnds in an hour no problem. I could whip out 50 on my lunch hour for that evenings shooting and still have time to eat and get back to work. For a plinker, or more casual shooter there is nothing at all wrong with that set up. If you shoot 50-100 rnds a week you'll be more than happy. Yeah, people will give you a hard time about it, but who cares, it's your life, time and money.
But... last Fall I got interested in IDPA and knew my useage rate was going to increase significantly. I also sold my 1911 and the old single action was long gone, so I was done to .38 target shooting and in the market for a .357 for IDPA. After being beat on at the club by the Dillon users I stopped by the Dillon booth at SHOT and got the run down from the factory guys. I now own a Square Deal and am mostly satisfied with it. At first the plan was to use it for both loads, but the adjustments are just not built for easy changes, so it does .357 exclusively and the Lee will be dedicated to .38 target loads if I ever do that again
The Square Deal is not the fastest or flashiest Dillon, but it can make you 100 rounds really fast, like 15 minutes if you're organized and is capable of a lot more in an hours time. It appears very well built and should last a lifetime.
My conclusion is, if you need maximum production in the shortest amount of time, Dillon wins no sweat. But if you are a newb on a limited budget or shoot more than one caliber in smaller quantities you will not go wrong with the Lee Turret.
