of course it depends on your play style and roster but it seems that neji is better in almost every case. His ability to reduce *lies cd round1 aswell as his chase reducing his own cd, meaning he can essentially allow you to use your pos 1 mystery every round, plus he recovers chakra each round and give himself "endure" to be more tanky, he is a very very good support character who could synergize well in literally thousands of possible lineups

Personally I have only seen one person using the brothers but that was a player who had almost a 1 million power advantage over the person below him in the rankings, so he/she is probably just messing around, and sure they revive, but its only with 20% health, so unless you are consistently facing people much weaker than yourself I cant see their revival actually having any impact

I have neither and I am also not a top tier player, I just collect characters and am always trying new teams, I am here for fun not paid competition but from my perspective I cant see a solid argument to choose the brothers over neji. Not only is neji common in china and fairly common here among the "sweats" but just from my own premature team ideas on konoha proxy I could see far more use for him, even without running any current meta characters
