The Question of the anniversary b1 tosh or b1 bichigo ?
First of all i see alot of posts in this subreddit questioning about that , to the point that there is alot of misinformation spreading by some players i doubt that they even play the game :
1 : bichigo is not stronger or better than toshiro , the latter is much stronger than bichigo by a lot ( any one tells the opposite knows nothing and dont play the game)
2 : b1 bichigo although it makes the character easier to play and makes the rotation faster with an additional CD for the overcaping CR but it still not that increase of a dps for the character like the b1 toshiro does , that give him 24 % all skill dmg bonus
So in conclusion in term of dps :
B0 tosh > b0 bichigo
B1 tosh > b1 bichigo
But if you dont have kenny and dont wanna pull for him , forget all that and get him but if not then bichigo's value is not great at all even if white is coming kenny will remain better than him + tosh also will be replaced soon but he's a very good solid unit that will carry your spirit team another 6 months if you have a b0 aizen
