Three Cheers For Sweet Revenge

Se-jun Lee, the guildmaster of the Messiah Guild that would bring salvation to the world.
"Let us save the world together. Let's put an end to this nightmare." The whole world celebrated the hero's appearance, and I became his comrade.

Yada yada yada MC gets betrayed and killed, only to go back in time to the moment he became a player.

Manga has same dungeon concept as Solo Levelling, I personally like the guy more as well.

Henry Morris was an 8-circled wizard who was a legend- one of the founding fathers who helped his friend become the king of a unified empire. After the son took over the throne, Henry was executed with the false accusation of leading a rebellion against the empire. He then wakes up in the body of young Henry Morris, the eldest of a baron family, who also happened to have the same name. By re-learning magic and swordsmanship, Henry attempts to gain enough power to exact his revenge.

Summary:
Junpei Takeda, a high school student, is childhood friends with Noriko Tatsumiya and the bully Kido Shouta. One day, during the usual course of bullying Junpei, they were suddenly summoned to a different world by the whim of "God". Summoned Heroes with cheats, or so he thought. It turns out Junpei's stats were worse than an average farmer. Tricked into a deathly labyrinth by the only one he trusts, he walks the journey for revenge.

A lot of annoying characters, fun to se

Long story short: strongest man on Earth is killed by one of his colleagues. 20 years later he's resurrected, and ready to find the bastard who killed him.

SO GLAD THIS ISN'T A PROMO ANYMORE, IT'S SO GOOD

Basically a story-based anthology-like series. Main character transmigrates into a character of some story and beats down the cheating bastards and villains/villainesses.

The gratifying thing imo is how clever the MC is and how everything basically always works in her favour. She's no Mary Sue and the revenge she serves is almost always extremely satisfying.

After overthrowing the devil, the Saintess and her colleagues were executed for treason. Reborn again, she decides to take revenge.

Deciding to eliminate the kingdom, the warrior, and all those who betrayed her!

I really like the "good turned bad" type so I really like this so far. MC got that crazy bloodthirsty look in her eyes and I'm living for it.

Betrayed and murdered by her own husband and family, Iris's life flashes before her eyes - including her previous one in modern times! With this new knowledge, she returns to before she was ever married, and is determined to exact revenge and stay alive.

Now, I really love this manga, but it isn't the type of revenge that gets my blood pumping like some others on this list (this manga is more the revenge/romance/feel good type)

Queen Kristina was framed by her half-sister and thereby executed at the age of 16.
16 years later, amidst the festivities in honour of the Queen’s birthday, a young girl is awash with nostalgia. Theresia, the daughter of a duke.
Her butler whispers in her ear: "How long do you intend to have me protect you?"
This young girl is none other than the former Queen, her reincarnation made possible after striking a deal with the alluring demon before her!
Not enough chapters, looks promising though

The weak prince of an insignificant country, Davey.
After becoming comatose, his soul escaped to a temple where the souls of heroes gathered.
He trained for a thousand years and has now returned as a max level hero!
“Just you guys wait, I’m gonna face you all head on!”

So far so good, OP MC, only thing im concerned about is romance and how big a role revenge will play in this manga. Edit: dropped this manga, annoying af characters that you just can't stand

I was bullied by everyone, so in return I'm going to slaughter them all.
Taking inspiration from the 31 days of the calendar, the uber popular girl group Calendrier was formed. Behind the bubbly appearance, in the shadows, there is one member that is bullied by the others on a daily face. "If you can't smile, then neither will the fans."
She is willing to do anything to regain the smile that was robbed by her group.

It's pretty exhilarating to read, this manga is a guilty pleasure for murder
