I have used a single stage press for many years (over 30). That being said, I also own two progressive presses (Dillon 550s).
I use different presses for different things.
I shoot a LOT more than 200-300 rounds a month, especially with handguns. I load most of my handgun ammo on progressive presses because I am looking for volume. I typically load 1000 or more at a time.
That being said, I use my single stage press a lot. I typically load all my rifle ammo on a single stage press. Sometimes I am too lazy to change calibers on my progressive loaders, so I will use my single stage press. Sometimes I want to play around with a load where I am only loading a few rounds and I use a single stage press.
So, no, I don't prefer a single stage press but I see this as have a variety of tools available and choosing the right tool for the job.
If you are trying to decide on what to buy and you are loading a few hundred rounds a month, then a single stage press is fine. Like some others have mentioned, I often just find loading to be relaxing and something productive to do, so I am not always in a big hurry.
