ya nice one.Gai and Lee r both experts of taijutsu.But Gai might not crumble under genjutsu users as he said during the fight tht he interferred during itachi and kisame came to take naruto before during like 138 manga chapter or sometime between it(i am not sure of the exact chapter but there is....somewhere in the manga).Otherwise i agree to u.
Gai simply avoided itachis tsukyomi by not looking into itachis eyes and looking at his feet.
However later in the manga itachi used his finger to plant a genjutsu onto naruto, and itachi also said he can use any part of his body to cast genjutsu.
Genjutsu isnt limited to just eye techs, taijutsu requires no chakra molding.
Lee and Gai cannot mold their chakra (physical/spiritual) to make ninjutsu or genjutsu.
To block or dispel a genjutsu requires that capability, so once lee or gai are under a genjutsu-they have lost immediately.
Im not saying gai or lee are weak, im just saying against most if not all genjutsu users they are screwed, and theyd also have a tough time dealing with ninjutsu as well..
Kakashi honestly seems half bored with Gai as his rival etc, and i am pretty sure Kakashi could own Gai.
Kakashi is certainly faster than Gai, and Kisame is DEFINITELY stronger than Gai.
Gai's taijutsu wasnt doing anything to Kisame, hell kisame was having a great time playing around with him.
Gai's a standard Jounin.
Lees a standard Chuunin.
In theory Gai could become a high levelled Jounin, and Lee the same, but thats there peak and itd take scrutinous amounts of work and years for them to achieve it.
The gate openers are there trump moves which make them a lot more powerful, it makes them temporarily stronger than kages, however note the word temporary, VERY temporary.
And after that they require a lot of time to regenerate and heal.
1vs1 gates makes it simply a tie/draw because both will be out cold at the end.
