Most gaming keyboards have polling rates of 1,000-8,000 Hz making them comparable or better than button boxes. With many button boxes there is a way of testing the latency of the presses. I’m not sure if there are any benchmark tools to do something similar for the keyboard, but thankfully this site has run latency tests on over 100 gaming keyboards. Some have latencies less than 1ms, which is the typical advertised latency of most button boxes (e.g., Cedrus and Chronos). Another feature of some high end gaming keyboards is individual key lighting, so you can highlight the keys you want the subjects to press.
