Kaneki is Currently Stronger Than Eto

After his unprecedented transformation in the climax of Tokyo Ghoul:re, Ken Kaneki has gained power rivaling that of the CCG‘s greatest foes. By becoming the Dragon and attaining an SS~ rating, Kaneki has clearly surpassed the once-dominant Eto Yoshimura for the title of strongest known ghoul.

The Making of an Absolute Monster – Kaneki‘s Evolution to Dragon

Kaneki‘s path to his Dragon power-up began during the Rushima Landing Operation Arc. After sustaining critical injuries from Furuta and accepting his identity as Kaneki once again, he turned the tables by ambushing and brutally consuming the bodies of nearly the entire Oggai squad. He deliberately targeted the unique Kakuhou organs implanted within each of the Quinx squads, allowing him to assimilate the foreign Rc cells. Furuta compared it to "absorbing experience points in an instant."

Furuta: "So you took them all…You ate more than 200 Oggai…"

This massive boost in Rc factor levels still paled in comparison to the final act of consuming Furuta himself – or more specifically, the Rize Kamishiro nucleus embedded within him. Per Furuta‘s own confession, this nucleus amounted to over 600 years worth of stored Rc cell stockpiles, created with the sole purpose of birthing the Dragon.

Furuta: "For the sake of giving birth to you, the Dragon…"

Upon absorbing this massive nucleus, Kaneki‘s body almost instantaneously mutated into the Dragon kakuja. This resulted in exponential growth of biomass with innumerable red Rc tendrils, mouths of gnashing teeth, and compound eyes flourishing uncontrolled across the gigantic body. The Dragon‘s highly concentrated Rc cells enabled extreme shape-shifting regeneration that could withstand even frame-0 gas attacks by Arima Squad soldiers.

Amon: "That thing is still mutating…"

In this ultimate form, Kaneki had long surpassed any conventional RC cell factor levels or kagune quality seen previously in the series. He had become a sentient and ever-growing organic superstructure capable of subsuming entire city blocks, with almost no viable methods left to combat him.

The Indomitable One-Eyed Owl‘s Abilities

Et Yoshimura first demonstrated her prowess as a premier ukaku-type ghoul from a young age, swiftly mastering use of her kagune. Under her father Yoshimura‘s guidance and through self-experimentation by implanting extra kakuhou, she evolved an exceptionally durable, full-body owl kakuja armor. This granted Eto a host of dynamic combat abilities against even top-tier CCG foes.

Some of her notable feats across the original and :re series include:

• Matching Kishou Arima in battle, destroying much of the 23rd ward
• Surviving ambushes/attacks from Special Class Furuta, Hanbee Abara, and Squad 0
• Regenerating after having near 100% of her body pulverized by Quinque steel
• Consuming her father‘s kagune as additional power boost

In terms of intelligence gathering, planning, psychological manipulation and sheer determination – few could equal Eto. Whether battling whilst maniacally reciting literature or lecturing foes on ghoul rights, she firmly backed her ideals through exemplary kagune use and physical resilience. Even Special Class Investigator UI Koori assessed her as:

Koori: "Your insight, judgment, strategy and technique at manipulating both sides of the conflict far exceed my own."

However, Eto was also prone to impulsiveness when enraged and making miscalculations against CCG resources. She failed to eliminate Arima when she had the upper hand, and later lost decisively in a rematch after Squad 0 wounded her.

The Decisive Factor – Kaneki‘s Dragon Transformation

While the One-Eyed Owl demonstrated herself as one of the most powerful kakujas in Tokyo Ghoul history, the series climax made clear that Kaneki‘s final mutation as Dragon eclipsed all previous ghoul abilities shown thus far. Some key advantages include:

Raw Strength: The Dragon‘s giant mass enabled brute force destruction that tore through cityscapes and buildings with ease.

Extreme Regeneration: Highly concentrated RC cells allowed near-instantaneous healing from all forms of damage.

Absorbtion: Kaneki actively assimilated all biomass he encountered while eliminating ghoul/human differentiation.

Furthermore, citing character statements helps establish the vast power discrepancy achieved:

Amon: "An unknown being that even Arima couldn‘t stop!"

Saeki: "Dragon…a godlike being we could not hope to fight."

In the end, whereas Eto fought fiercely relying on her experience and cunning, Kaneki‘s forbidden sacrifice enabled him to utterly shed his humanity for pure innate ghoul strength beyond all bounds – truly becoming the Dragon feared in ghoul prophecy of old.

Core Attributes Comparison

Based on this overview, Ken Kaneki‘s final evolution granted him maximum values in the key combat attributes, explaining his well-earned status as the current strongest known ghoul in Tokyo Ghoul.
