The same reason BMC still sells, despite the home/craftbrewing boom. The same reason why Windows is still in use when GNU/Linux is superior in almost every way: people aren't always logical.
Seriously, for a while there was concern that aluminum was linked to Alheimers. This has pretty much been disproven, but like most urban legends they tend to have staying power. Also, certain cleaning products can be used on SS and not on aluminum and vise versa. Palmer says it best in this line from "How To Brew"

Another very real reason: people like shine. Aluminum dulls after exposure to air while SS does not (to such an extent). In restaurants where appearance matters SS would have a reputation for being "better" despite the fact that it doesn't affect cooking properties.
The final answer: Everyone's defintiion of better is different. Choice is good.
