If you want an even black on concrete, water based stain is the route. π€
Acid stain reacts chemically with the minerals in your particular slab, which is why the color varies naturally across the surface and why no two acid stained floors come out the same. For a great many projects that variation is the whole point, and it is what makes stained concrete read like natural stone.
With ColorWave the color stays consistent and predictable across the slab. That also means you can plan around it, which matters when black has to work with cabinetry, fixtures or a wall color already decided.
The protection stack is doing real work here as well. ColorWave has to be sealed, because it is water based and the color carries no protection of its own. AcquaSeal locks it in. ProWax then goes over the top as a sacrificial layer, so traffic and grit wear down the wax rather than the sealer underneath it. Wax is inexpensive to recoat. Stripping and resealing a whole floor is not.
That matters more on black than on anything else, because black shows scuffs and wear faster than lighter colors do.
