Which fighter is better in offensive counter-air role?

As I understand it, both Tornado F2/F3 and Mirage 2000C/5F were
designed more or less as bomber interceptors, not as a dedicated air
superiority fighter like F-15A/C.

After the end of Cold War, they had to adapt to new roles in entirely
different envirionments. Which of the two managed to adapt more
successfully? I know none of them scored a single kill over Iraq and
former Yugoslavia, but at least they contributed to the effort to
enforce the no-fly-zones.
