I like Stilt-Man!

Granted, the character, when written properly and in-character, is not a joke-villain, and not a professional leg-breaker. He's simply one of those characters that gets thrown into the disrespect-list simply because so many nerds, I mean, Marvel fans, expect all the bad guys to be a Green Goblin, Electro, or Dr. Doom.

Stilt-Man is like what most of Flash's rogues gallery was before the majority of the most famous members murdered a de-powered Kid Flash in cold blood. The villain's only real stupid mistake is to continue to take up residence in a major city where he's quite likely to casually cross paths with swinging super-heroes and flying super-heroes. That alone makes him no less of a genius than Doctor Octopus, the Wizard, or Doctor Doom.

Any dude whose primary gimmick is quick getaways and easy access to stuff up high isn't someone that should be mocked or used as a throw-away death (although that's what happened to Kite-Man, as he died an off-panel death in 52). Stilt-Man is great for the gratuitous fight that should be in almost every issue of a super hero comic book. He has also one a few fights. It isn't the sign of a bad character that most of his arch-enemies slightly out-class him. An armored dude with enhanced strength and elongated piledriver piston-legs isn't one to engage in innovation, and frankly if he started shooting death rays out of his wrists or became seriously dangerous then it would ruin the character.

Mind you, all it really takes to make me like a villain that some other reader believe is lame, a joke, or silly, is to be introduced to the character in one good story where the villain is treated suitably seriously.
