Carnage was forged on Earth and has therefore developed slightly more potent abilities than Venom. The character is actually a lot stronger than Venom, despite having been born from him. In fact, Carnage's strength is more forceful than both Venom and Spider-Man's.
The bond between the Carnage symbiote and Kasady was not as strong as the bond between Brock and the Venom symbiote. However, Cletus Kasady was also a serial killer and thought of as insane. As a result, Carnage is far more violent, powerful, and deadly than Venom.
In addition, Venom has come out on top as the victor in many battles with Symbiotes like Carnage, Hybrid, and Scream (all of which are arguably more powerful than he is).
Carnage and Venom have the same biology as both are symbiotes, and in the comics, he's actually the offspring of Venom. As such, he's more powerful than his “father”, and his bond with Kasady makes him a lot more violent than Venom.
It is possible that, because of the Enigma Force is such an old entity, Mjolnir has a preexisting relationship with it, making it accessible at the time of Venom's need.
Riot is stated by Venom to be the strongest and most brutal Symbiote. Through Venom, he had humiliated weaker symbiotes including Venom himself in combat.
Extremely loud sounds (or extremely high frequency sound waves) can shock the symbiote, and even cause him to separate from his host. Spider-Man discovered this not long after meeting Venom.
In the present, he attempts to use Eddie Brock to investigate Cletus Kasady, but is seemingly killed during a battle between the Venom and Carnage symbiotes and Barrison. However, he absorbs a piece of one of the symbiotes, which later revives him and causes his eyes to glow blue.
By eating Carnage, Venom is effectively returning his spawn back to his former "unborn" state within Venom's mass, not taking anything he didn't already have into his cells.
Venom is not the only symbiote user who does this. It is just a way to highlight how the union works. “We" implies a collective effort, and Venom is the product of a melding between a man and an extraterrestrial creature. Two creatures uniting on a very specific kind of wedding and acting now as a singular entity.
In the movie, Riot was not a child of Venom but was an alien that arrived on Earth at the same time as Venom. Furthermore, Riot was more equipped for battle and proved to be stronger than Venom every step of the way.
Personality. Carnage is a sentient being of pure evil, shown by how moments after the symbiote was born it wreaked havoc in Prison during its escape. Carnage also has a deep hatred for its father, Venom, wanting to kill him so that he could be the only symbiote on the planet and thus unstoppable.

The Toxin symbiote has a long and troubled history in the Marvel universe as both a villain and an anti-hero. Toxin's place in Venom and Carnage's genetic line and its difficulty with hosts have all helped define the symbiote and its ever-expanding place in the Marvel Universe.
Born from Carnage as the 1000th symbiote in its lineage, "Toxin" was feared to be the strongest and most dangerous of their race by both Carnage and Venom besides Knull. Shortly after being born, the symbiote united with police officer Pat Mulligan.
It attempted to forcibly bond itself to Spider-Man. Later the Vulturions attacked and Spider-Man forced him to take them all to a church tower. The bells rang to sound the hour, the symbiote felt the pain. The clanging of the church bells and Spider-Man's rejection of the symbiote weakened the alien.
However, Venom has a couple of key weaknesses that Spider-Man can exploit. High-frequency sonic technology will cause the symbiote to flee, even leading it to break its hold on the host. Fire is also something the symbiote is deathly afraid of - he will cower in the face of flames.
