One Punch Man is definitely the first anime somebody may think of when trying to compare To Be Hero with something. Both are parodies of the superhero genre, both have a very powerful main characters, both have a cast of zany and eccentric characters, and both have some cool fight scenes.
The main character of both series are perceived as invincible superheroes but is struggling with other aspects of their life - Saitama with his boredom and Ossan with the recognition of his daughter. Both series makes full use of their ridiculous slapstick humour but can also surprise the audience with its juxtaposition of comedic with serious and emotional scenes.
To Be Hero and Panty and Stocking both have crude anount of humor, including the same sexual and bathroom jokes. They are both action shows as well, with hilarious villains and slightly unlikable protagonists.

Over-the-top comedy is abound in both works, as well as over-the-top animation. They're both pretty short (To Be Hero is a collection of 11-minute episodes). Both Dead Leaves and To Be Hero like to bring up plot points and bombastically get rid of them within a blink of an eye. To Be Hero, however, is approximately 3 times the length of Dead Leaves in terms of both of their overall run times, so if you're worried that you may get burnt out on the excessive speed and crudeness of Dead Leaves, To Be Hero might leave you a little drained by the end of it.
