Depending on patience or perhaps productivity, and discounting auto feeders etc, a press is a press, is a press. As for dies, different brands/lots will be found within tolerance but one possibly a better fit for a particular chamber's tolerance. It's not what you have, it's what you do with it. (Those who go beyond a few reloads with a batch of cases know how they got that far.)
If you gather gear in batches, from yard/estate sales etc, you're bound to end up with extra die sets for a caliber. There will be ones that you never use, and maybe ones preferred for certain guns (chambers). At that point, box color can become like "Go Packers!" or a Ford/Chevy thing.
Those extra single stage presses can be designated for decapping, swaging primer crimps, case forming steps, etc. There's no substitute for room to set 'em up.
btw: Lee tools I won't load without after ~10yrs: Ram Prime, Univ de-capper, case trimmers/pilots, 1-flute neck chamfer tool, zip trim, collet neck sizers (say a dozen calibers). While I'm at it, SS pins to tumble brass 'wet'. (U/Sonic & vibrating methods are hungry and messy (dust, chemicals vs soap & water)..) :stirthepot:
