I'd still say it was a win in Reborns Gundam favor.
00-Raiser became a dead paperweight.
Reborns Gundam could still move, albeit with heavy damage and close to burned out GN Tau drives still managed to 'walk' away.
Between a fight with 0-Gundam(1 Gen) against the Exia R2(3.5 Gen)...obviously the Exia R2 would have a better chance to win.
It having superior tech and all as well as a much bigger sword.
If Ribbons had a more powerful mech...like the 1.5 Gundam, he would mop the floor with Setsuna.
Now does this not look like Wing Zero? This is as close to Wing Zero we can get in the AD world.
