More people probably recognize The Addams Family than The Munsters because there's been more adaptations of the former and The Munsters was inspired by the Addams Family comics with Universal wanting to do a sitcom with their monster movies to go off of. The Munsters as pop culture is a lot more contained to the 60s-70s. Allan Burns, one of the writers for The Munsters, even said "We sort of stole the idea from Charles Addams and his New Yorker cartoons.... Because Universal owned the Frankenstein character and the Dracula character for movie rights, they decided to take their characters instead of the characters we had written."
The Munsters did have a revival in the late 80s, but when that ended there wasn't anything produced for two decades until an attempt at a darker and edgier reboot in 2012 that got canceled after the pilot was produced followed by a decade long gap until the poorly received Rob Zombie movie in 2022. The Addams Family by comparison has more consistently had stuff that was well received being made and still has new stuff actively being made for it. The Addams Family was also a lot more popular in the 90s and 00s due to a cartoon and live action films and tv series being made in the 90s and being aired a lot when The Munsters just didn't have anything going on other than syndicated reruns.
Probably doesn't help that Universal can be very controlling of their IPs. Frankenstein is public domain, but Universal has gone after people for portraying the monster as the flat top, bolt on neck version they own the rights to for example.
Personally my introduction to The Addams Family was reruns of the 90s cartoon on Cartoon Network and the live action films airing on cable and a lot of people still love those versions especially. I just didn't have the same awareness of The Munsters as a kid beyond occasionally seeing it on TVLand if staying up late.
