Its not known who is faster. It is generally believed that the raikage is faster, but it is really unknown since guy has not displayed any real speed feats in the 6th ir 7th gates. I personally beleive that gai is probably even or slightly faster in the 7th gate, but thats just me.
In taijutsu, guy has clearly shown feats of taijutsu that are greater than almost anyone in the manga with the power of the gates. He is considered one of the most powerful taijutsu users in the NV.
raikage is superior both in speed and strength .....its mainly becoz...he is a nin-taijutsu user...though guy will be a tough opponent for him....guy 7th gate vs raikage fully charged.....hmmm a fight worth watching...
The search bar.
Well seeing as we've never seen Guy go into the 8th gate, this thread is pointless. And please use hte search bar.
