I've had some of nearly every common loading equipment except Dillon. They all have their god/bad issues, but the one piece I truly do like is the LoadMaster, I use it in 9mm, 38, 357, 40, 45, and 38S&W.
I've honestly never had any issue with any of their dies, presses, or scales that couldn't be overcome with some common sense.
But I've never had the APP, and would not have a use for it now, anyway, with all the other stuff filling my bench.
The people at LEE seem to have a penchant for innovation, believing that it IS possible to build a better mousetrap, and they do pretty good.
I like their bullet molds, but my favorites still are some old Lyman and Lachmiller aged cast-iron molds.
However, I am just an awful lot old-school on bullet sizing. I feel that the bullet MUST be stabilized at its nose while sizing. Thus the old Lyman 450, with a G, H, & I die is a must for truly accurate cast, sized, lubed bullets. The APP offers speed, but at a cost, I feel.
Innovation. That's the word.
