My first press was a Lee Turret, and I got very good service out of it. Back then I was a 100-200 round a month shooter. When I got into competition, I picked up a Dillon 550 (2000+ rounds a month). Once you get the Dillon set up, it is fast.
I kept the turret though, I use it for my small volume ammo (.45 LC, most rifle, etc) because you can easily change calibers. I can use it as a single stage, or a semi progressive depending on dies and caliber. I also use it as a decapping station (I like to decap before I clean).
The hardest part about setting up the Dillon is adjusting the powder measure. It takes a fair amount of time to get it right. I use the auto disk on the Lee. It is throws a pretty consistent charge, and all you have to do is write down which chamber throws what charge for what powder. It is limited on fine tuning, but since it loads mostly my fun ammo, getting it close to where I wanna be charge wise is fine, .1 low or high is not going to bother me for loads that are generally a notch above minimum. My old auto disk seems a bit hokey with the screws to attach the hopper, I keep worrying that I am going to wear out the threaded holes, but it seems to still be okay after two decades. I got a Lee Perfect Powder measure (drum type versus disk) and that works very well too.
With the Lee I load 50-150 rounds at a time. For my Dillon, I get it set up and load a thousand or two before I go through the pain of switching calibers.
The only complaint I had with my press is that the primers just dropped into the base and sat there, you had to unbolt the press to empty it. I glued some half sections of pipe inside to channel it and drilled holes in my table and put a paint can under it so they drop straight through. I think they may have fixed that with the newer ones, or at least fixed in on the other turret press they now offer with the different base (which they call the Classic, kinda odd since it is the newer model.).
