Aren't Ghouls pushing at least high-supersonic to hypersonic speeds for reaction speed considering they can make trouble for CCG agents?
Can still picture Spidey possibly taking this match, but with difficulty. Kaneki's regeneration is impressive as such where he can regenerate damaged organs and body parts rather quickly and despite his superhuman durability to impact-type attacks, Spidey is still vulnerable to cutting damage from bladed attacks that would take longer for him to recover from. He can sustain this type of damage from Kaneki's kagune attacks. At the same time though, Spidey's strength is more greater, his webbing would give Kaneki fits if the web-slinger managed to web him up (which also gives him a ranged advantage in combat) and obviously gaining an additional edge with precog via his spider sense.
So factoring things:
In-Character: Spider-Man 60/40. Without knowing what he's in for, Spidey would be likely to not take the match as seriously since he normally toys with his foes to get them riled up and this could be exploited by Kaneki since he's more than willing to kill here. Still, Spidey could take this in most scenarios assuming he keeps his distance from Kaneki and resorts to using web attacks to ensnare him before engaging in close-range combat.
Bloodlusted: Spider-Man 70/30. With the gloves off, Spidey would milk his webbing to immediately try finishing things before going into close combat which raises the difficulty for Kaneki here. Kaneki could still possibly take this, but it would be more difficult for him with a bloodlusted Spidey.
