Berserker is both faster and can one shot with a casual swing so yeah he wins.
Though really funny how you banned God Hand, Berserker's main feature.
@Fehafare: How will Berserker hit him if he uses flight and remains in the air? He'd be out of his range.
His bankai is multi city block+ though, doubt if Berserker can tank it
Why would Komamura use flight right off the bat, then use KTM?
He usually summons his Bankai while standing on a surface to kill his opponent as quickly as possible.
@Fehafare: I doubt if he's faster. FSN Saber is just mach 14 or 15, right? Komamura could keep up with Tousen, who blitzed base grimmjow, who blitzed bankai Ichigo, who's calced to be mach 23+.
And when did Berserker slap away Excalibur? If I remember correctly, he got killed by Archer's arrows and a fake Caliburn's normal stab
Yeah that... or you look at the rest of his feats that place him at supersonic+
And again, mach 15 is for movement speed only. She can dash at mach 45 for combat purposes (it's actually possible that it's higher than that, potentially mach 90 but that hasn't be confirmed yet) and has the reactions on the same level. Berserker can match her in that department, so even with the whole mach 23 Berserker would still be nearly twice as fast.
And you remember so because you base you knowledge off on god knows what non canon shit you managed to catch onto. Archer's arrow didn't actually put a real scratch on him. Caliburn is one of the bigger PIS moments in entire Fate and it was implied that it had a special property to do so, more so it was activated from inside of him.
And he done so with Excalibur in Heaven's Feel or during a bad end in Fate i don't actually remember exactly, it's one of those two.
