Me and Troj got into a fight about how strong Ichigo was compared to the other Shikai/Bankai in the game, and so we went into a huge fight, literally.
As some of you MIGHT have noticed if you weren't obsessively playing the game, there were 2 servers, in it me and Troj were having a war of every Bankai one at a time versus Ichigo. I played the Ichigo, he played everything. Note these are the updated versions.
Ichi Vs Hinamori: Arguable, it coulda went either way
Ichi Vs Ichi: Tie (It all came down to the final hit)
Ichi Vs Kira: Ichi Win
Ichi Vs Yumichika: Ichi
Ichi Vs Ikkaku: Ichi
Ichi Vs Renji: Renji
Ichi Vs Byakuya: Ichi
Ichi Vs Jiroubou: Jiroubou
Ichi Vs Hitsugaya: Ichigo
Ichi Vs Zaraki: Zaraki
Ichi Vs Mayuri kurotschi: Mayuri (He was left with 900 HP, one normal hit would have done him in)
Ichi vs Rukia: Ichi
Ichi Vs Ichimaru: Ichi
So in all, Ichigo can definitively beat 7 (that's more than half) of the other Shikais. The Hinamori match is disputable due to we had 2 rounds, the first time Troj lost hands down, the second match he attacked me before he even said start, and two more hits from me would have changed it all.
In all, Ichigo is indeed powerful, and when played smart, can beat almost any Shi/Ban. The Ones it DEFINATELY cannot beat is Zaraki and a WELL played Renji.
Note ALL of these matches were not done purely IchinUb Style, and mixed close range with Getsugas carefully mixed in. Most of these matches except for the Renji and Jiroubou were split decisions all deciding on one to two hits.
Overall This proves that an Ichigo can truly gain a huge advantage in the battlefield, but only when properly played.
PS: Troj is a Sore loser

I had to beat Kira 2 times in a row, Byakuya Twice in a Row (one time he ate Kidou and complained so hard), Rukia one time I was D/ced right before it started, second fight he kept cheating. It's all so funny. But I will Admit Troj is one of the best I've fought.
PS: Ichi fight with normal melee versus melee, ABSOLUTELY no Getsugas.
