Which horses were truly great?

[SniperSB23]

I'm already having this debate on another forum and it seems as good a time as any to bring it here. Which horses were truly great? For the purposes of this thread great means they were both brilliant and accomplished and the elite of the elite. Ghostzapper was brilliant but not accomplished enough to fit the definition. Cigar was accomplished but not brilliant enough to fit the definition. Here is who I believe fits the truly great label. Who would you remove or add?

I'm only talking North American based horses and not giving anyone a break cause they are a filly. If their biggest accomplishment is that they beat the boys and are great "for a filly" that doesn't count. All of these horses beat the boys every race and would be otherwordly if they were fillies.
