Round 1
Darg
* Megumi literally has no piercing resistance feats and Cid cuts REALLY good
* Megumi's set up requires time to do
* Cid is faster and takes first action
* Cid is durable
* Zealot is faster, mobile and hyperlethal
* Garou is fast, hits hard and his opponent is nebulous
Abe
* Megumi is faster
* Megimu has similar stats otherwise to Cid
* The summons are functionally invulnerable to Cid
* Yuji has better stats than Zealot
* Todo is provably faster, has better strength + durability but worse skill though can compensate with teleportation

Round 2
Darg
* Stat posting
* Cid attack speed VERY good
* The 'functional invulnerability' really only applies to punches
* Megumi's 'most likely actions' aren't gonna work
* Megumi scaling bad
* Cid failing to bullet time isn't a real fail
* There's a ton of wonky scaling going on
* Garou just all around > Todo

Abe
* Cid isn't actually a bullet timer
* Clone stuff
* Yuji > Zealot in terms of strength and durability
* Todo has strength, durability and speed advantage + teleportation

As I've read through the rounds, I think Abe has a huge issue by Round 2 where while he makes a lot of points that were already stated. Darg in comparison spends a lot of time evolving his own points, calling Abe's attacks into question as well as reinforcing earlier points he had made while making more direct and specific comparisons.

Darg is the winner.
