Historically,When Guan Yu was captured by Cao Cao, Guan Yu stated that Zhang Fei was about twice as strong as him.What are your views on this?I believe that when Guan Yu returned to Liu Bei,Zhang fei had a few fights with Guan yu,But was an Even fight.Zhang Fei also helf off alot of people on the bridge(I can't remember the Battle name) nearly all by himself and was successful,However Guan Yu Killed many in fan castle,But lost.I personally believe Zhang fei was strongest in a competition of like arm wrestling and weight lifting,But Guan Yu would be stronger in the sence that he fights well,And lifts a very heavy weapon.Also he was smart(i think) and was a very good leader.
I would also like to bring up that the 3 "Brothers" were really brothers,I mean In the game it says they are brothers,However historically It says that they were close friends.They often slept in the same bed(sounds wrong...) and were close friends.
