Before the Thousand Sunny chase lasted a quarter of the arc, even enraged Big Mom was kinda threatening. Oda balanced her goofiness with some solid devastation. Knocking out Judge with utmost ease, blocking Kong Gun with just haki, being able to make anyone who wasn't stupidly brave or strong die via her devil fruit.. Like, again, until Oda made Big Mom blunder 30x times, she wasn't bad.
Not a good character. But her presentation wasn't bad.
You even have Katakuri who Oda spent so much time building up, presenting as a bigger threat to Luffy and to the success of the assassination than Linlin herself. In wano, it's pretty much... The antagonists being dunked on lol.
