I bought a Lee Challenger press back in '88 and loaded thousands of rifle rounds and magnum pistol rounds with it with exactly zero problems. When Lee came out with the heavier steel assemblies for the handle and ram movement, I bought a kit for the Challenger press. It now serves duty as a sizing press for my cast projectiles via the push-through sizing dies after the Hi-Tek coating is done, as a de-priming and priming press, and for use with my Hornady bullet-puller.
I don't like the word "better" when comparing most presses. Rather, "preferable" makes more sense to me. I grew up with a Rockchucker and for a long time, I really liked that "cam over" travel on the handle when I was doing all my loading single-stage.
All reloading equipment produces the same finished product--a loaded round. Some do it in ways and via mechanical movements that are more preferable to others, less so to the rest. The Dillon 550 has an almost cult-like following in the progressive crowd, even though it is a manual indexing press--and the manual indexing drove me up the wall. I prefer the 650. But it doesn't make the 650 "better," but rather more preferable for my purposes and preferences.
