It's more that WWF had a different style than WCW, if that makes sense.
WCW had its roots in traditional southern pro-wrestling. WWF embraced a more "show" oriented style. It gained prominence by basically forcing other companies in the territories out of business through a variety of anti-competitive and unethical tactics. A lot of the guys who ran those territories ended up with Jim Crockett Productions, which later got bought by Ted Turner and became WCW.
As a result, WCW reflected traditional pro-wrestling. While WWF leaned into a sort of "cartoony-ness" at the time, WCW presented itself as being an actual sport full of over-the-top characters. It felt more "real" without going overboard into workrate mark territory, if that makes sense.
A lot of the booking was shit (run-ins galore) but the stories were fun at its prime and WWF was hot dogshit until Austin really started going.
