Aizen easily. He always has a plan regardless of how dangerous and overkill his opponent truely is. To a power absorbing machine to a "Anti-Yhwach" machine. Aizen can do both now since when were you under the illusion yhwach fodderizes? I will have you know Aizen is worthy of chair-sama who was able to stomp the likes of yhwach regardless. If the battle gets too overkill,
Tite Kubo as the creator of bleach would erase both effortlessly. This is a stomp.

E for aizen plans beyond everything. Even if he losses, This is just part of his plan and if he tricks Yhwach into winning against him. That's just part of his plan and the plan being over is just part of his plan. Aizen planned joke battle wiki's existence with infinite diagram blueprints. And that is only downplaying aizen for i have fell into his illusions and so on. Sosuke Aizen doesn't just plan since the reader of this comment. He plans before YHWACH'S Age as well. Before yhwach was born infinite years ago, Aizen planned for this whole battle, His wank and his creation and he was born even before yhwach's grandfather was born. S T O M P for this is just mere facts and no form of downplay.
