I've been reloading almost 50 years. Originally I went with the Lee prep tools and I'm still using them.
Like others, I chuck the case holder base in a light portable drill for the case trimmer. Then I spin it against the inside/outside chamfer tool. I have the RCBS tool, but it chatters against my 45-70 brass. The Lee one does not.
I use the RCBS primer pocket swager for military crimped primer pockets. It irons them out nicely, and I think it's easier than using a reamer. I have two carbide primer pocket reamers, but I only use those for my varmint caliber cases. I don't bother with handgun cases or my larger rifle brass. I also have a flash hole uniformer for the varmint brass. These are operations that only need to be done once, and only if you're obsessive compulsive about your brass. I do it once on my new brass for first loading.
A lot depends upon how much you will be loading and shooting. Straight wall cases will "grow/stretch" very little. Bottle neck cases more so. Magnum belted cases, will need trimmed every 2-3 loadings.
If I were loading .223 I wouldn't bother. I would only load those 2-4 times then toss them. They're common pickups for free at most ranges.
Over all, I prep my brass--primer pocket, flash hole, trim length, inside/outside chamfer only on my .22 hornet, 22-250, .222 Rem, 7x57mm, and .308. My new 45-70 cases get flash hole and length trims. Handgun brass gets nothing.
Unless you are loading a ton of bottle neck cases/year, hand tools are sufficient. You really don't need to do it all that often. Not for every loading, certainly.
