Security issues in Apache will be found and reported before bugs get found
Apache is open source which allows people to audit the source code easily.
IIS6 however, isn't open source and it's often more time-consuming to find
bugs. It's difficult to determine right now if IIS6 has more security
issues than Apache for that reason. It could have less; it could have more,
since it isn't open-source, only time will tell.
I personally notice Apache security patches/new releases are out quicker
If I were to receive a security bulletin detailing a security issue in
Apache, I could go to the affected part and fix it and recompile. You can't
do that with IIS.
I would say that those are some of many reasons Apache have been the most
widespread http server since 1996
