Both MCs have abnormal abilities. In voice the MC has heightened hearing therefore making her hear sounds and voices that no one else can hear. While in Children of a lesser god, the MC is able to relive the moments of victims deaths just by touching them or using a photo of them. Both MCs use their powers to their advantage to solve cases as they both work in a police enviroment. In both shows there is a serial killer. Both have partners that are not romantically interested in eachother. Though in children of a lesser god there may be some questionable scenes thrown around - that's up to your interpretation.

Both have fantasy element. COALG focus more on mystery and conspiracy while Island go deeper into the fantasy story. But both have subtle romance story. If you like fantasy drama with a slight romance, both dramas are definitely recommended

Both dramas have one main lead with shamanic abilities. Religion is also present in both of them even if in a negative vibe in Children of a Lesser God.
The protagonists in both shows have different sets of skills and team together (reluctantly at the beginning) to defeat evil.

Children of a Lesser God is somewhat lighter in tone (having some comedic moments here and there) and the antagonist isn't a demon, but a cult organization. It still does have some creepy and bloody elements and some pretty disturbing scenes of child abuse.
The Guest is more of a pure horror drama and has a bleaker tone in general. The antagonist here is a poweful evil spirit and not just evil human beings.

Overall I found The Guest to be the superior of the two, but Children of a Lesser God is an interesting drama as well and might deserve a watch!

two dramas explore same concept about religious cults and stronger people behind them. Both were aired by OCN which is famous for it's mystery thrillers.

A tragedy resulting in multiple deaths; a conspiracy by multiple entities to cover up the truth and try to kill anyone who is investigating the incident. The investigating team consisting of people who are closely tide to the tragedy through loss of family and their occupations.

strong FML that has premonition skills
both are cops
ML that does not trust the FML at first resulting in trgic lost to the ML
and common seek of justice/vengeance by tracking the muderer
involvement of greater god plans and question about destiny

Thriller by the same OCN. It has a similar atmosphere also the main detective is also like a genius.

These two dramas have similar story. Both focusses on a tragic event in the past (after which the main characters separated) and how it affects their present lives when they meet and starts remembering their past.

- Cults
- Suspense
- Thriller
- Glitch is sci-fic cult based whereas COALG is Christianity
- Investigation
- Abduction

Both dramas have a similar investigation duo, both female leads have a close connection to dead people and can interact with them. Both female leads have a family that has many secrets. And both dramas deal with crimes and children that are somehow involved in those.

Both series shares a cult like organization, leading people to believe in lies and covering crimes by involving past incidents that has nothing to do with an event happening in present. The lives of people closely tied with each other, it shares crimes of human beings.
People who are trying so hard to uncover truth & powerful people supporting the cults are creating obstacles.

Both crimes are due to religious fanatics/cults. In both the police are smart and have ties from their youths.

Both shows follow the forgotten childhood friends trope.
Both in which the Main Lead have memory loss from their childhood due to traumatic experiences. The forgotten childhood friends are disguised within the story and slowly make its way to the surface.
Children of a lesser God focuses more on the childhood friends aftermath, which is something Quiz of God didn't do.
Children of a lesser God is about detectives investigating a hidden underlying Cult while Quiz of God is about a team of Autopsy Doctors working with the Police to find out who is the hidden mastermind.
Both in which the Villains personally know the Main Lead so you can emphathize their actions.

Both MCs have a psychic ability. In both shows, the MCs are able to look through memories of other people through touching them. Both MCs work in a police base setting and use their powers in order to get closer to the case. While in Memorist, everyone accepts the fact the MC is a psychic but in Children of a lesser god, it is not the case. The MC struggles to convince people that her powers are legitimate and it becomes one of her struggles throughout the show. Another difference is that in memorist the MC can look through all memories but in Children of a lesser god the MC can only look through the moments before of the victims death.
