I load for over 40 years and use both single stage and progressive press. The comments old guys I find interesting.
all the new guys want progressive and all the old one want single stage, “as I see it.”
The problem is that people who start on a progressive press don't know the feel or the sounds they are familiar with. Needless to say lots of screw ups. Very few people start with a progressive with out a lot of problems. Like seizer die set down to far, or a piece of brass didn’t feel quite right. There is an art to being a good loader, lots of little tricks. After loading thousands and thousands of rounds before I moved to a progressive presses and still there are times I will use a single stage press. This year I loaded over 100,000 rounds of different types.
There are times that I will not use a press or die such on my bench rest rifles with a tight neck. Just start slow and adhere to safety precautions
