For me the list of "top 5 Batman artists" pretty much begins and ends with Neal Adams. Without whom many other artists never would have drawn the character, or at best, their work would have been vastly different.
Such as Dick Giordano, Irv Novick, Jim Aparo, and Frank Miller. These are all artists whose work clearly evolved out of Adams' vision of the character, who brought Batman back to his mysterious avenger-of-the-night roots that Batman began as in his first year in 1939-1940, before Robin was added to the mix.
