So, when Kaneki tried to eat Hide, Touka took him on, and, according to Yoshimura, beat the *#@$ out of him. However, I feel like it wasn't a fair fight, seeing as Kaneki didn't know anything about how to use his kagune, what type of kagune Touka had, or even what types he was weak against. so, inexperienced and untrained as he was, Kaneki was obviously no match for someone who was familiar with their kagune and knew how to use it, therefore Touka had a guaranteed victory. However, if a experienced Rinkaku ghoul and an experienced Ukaku ghoul went for each others throats, who would win in the end? Ukaku ghouls have their speed and long-range projectiles, but don't have the stamina to match. Meanwhile Rinkaku ghouls have their sturdiness and extremely fast regeneration, but brittle, fragile kagune due to their RC Cells being more similar to liquids than that of other ghouls. Ukaku ghouls are weak against Koukaku ghouls, and strong against Bikaku ghouls. Rinkaku ghouls are weak against Bikaku ghouls, and strong against Koukaku ghouls. Who would win in a death match between the two?
If an experienced Rinkaku and equally experienced Ukaku went for each other, Rinkaku would have a higher chance of winning. They are only weak against Bikaku. In Chapter 13 of Tokyo Ghoul,
Furthermore, on the same chapter,
Shinohara said that RC cells of ghouls acts as an effective 'poison' to the types that are weak against them.
I would like to answer this question with my own hypothesis. I haven't done much research on tokyo ghoul combat but I have my fair share of knowledge on the subject.
A rinkaku ghoul would have a higher chance on defeating a ukaku ghoul on a one versus one situation. Their kagunes are quite brittle but by hardening their rinkaku (similar on how ukaku kagunes enter a crystallization state when firing). They could defend themselves against the ukaku onslaught.
However, if the rinkaku would attempt to focus on fighting the opponent at range. The further the rinkaku tentacle stretches, the more it becomes weaker as kagunes are based off of muscles. The further a muscle has been stretched, it could experience tearing or getting weaker.
Which means at a certain point, the ukaku could be able to pierce through the hard shell of the rinkaku kagune. But this is potentially a harder risk for a ukaku due to fighting at range, they would have to constantly avoid the rinkaku kagune.
