Because later, the Spitfire sorta phased out the Hurricane, even though the Hurricane was still used as a fighter on the Eastern Front by the Lend-Lease treaty. But it was usually used against ground targets, and in some cases, night fighting. At least, they experimented with night fighting. I'm not 100% on my Hurricane education
But the Spitfire is well known because it wasn't just used in WW2. The Israeli's used the Mk19 or something like that in 48' against the Arabs, and Egypt used them as well in some cases. The Hurricane, though a great plane to see fly and hear, just became obsolete like many before it.
