Yes, if you buy batteries for N * 100K $money, spending more money
on your charger is a good investment.
But if you have two batteries doing float-charge/long-run/tiny-load,
in a benign environment in a corner of your lab, the internal
variance between batteries in that same production lot, will
overshadow any imaginable benefit a fancy charger could bring.

They are for the same reasons they suffer cyclic use better.
But for a float/long-run application, it makes absolutely no difference.

Never attribute to malice what can adequately be explained by incompetence.
