Looking at the raw numbers of both of their
AP (16,89 megajoules vs
13 megajoules), Yor looks like stronger one of the two. However, it should be noted that the feat Brad scales to is done rather early on, and he gets considerably stronger over the course of the game. Brad can also further increase his strength with Joy and if we go by game stats, it multiplies his AP and dura between 2 to 3x.
Brad's inhuman
stamina-wise. He can tank slices, gunshots and powerful strikes with little impediment to his fighting ability, can fight while being heavily debuffed by severe withdrawal and can still fight with efficacy even while on fire, poisoned and under other status effects. This is without taking into account his healing items.
Brad most likely has Yor beat in this category.
In terms of
skill,
Brad is an immensely skilled martial artist who invented an entire martial arts style, and those taught to use it are by far the most efficient fighters in all of Olathe. He has demonstrated his prowess by defeating champion-class wrestlers in direct combat, learning other styles and incorporating their teachings just by reading their scrolls, using his style efficiently even against armed adversaries, ranging from swordsmen to gunslingers, and he can accomplish these even with both arms chopped off at the shoulder.
Yor is a member of the notorious Garden Assassins, who are known for their ability to take on entire military units single-handedly. She demonstrated her exceptional combat abilities by taking on and defeating an entire army of highly skilled assassins armed with a wide range of weapons, who were skilled enough that a senior member of Garden was impressed with them.
So
they should be about even in this category.
What really puts this in
Yor's favor are the
HH+ poison projectiles and
pressure points; While Brad resists Poison, his resistance definitely isn't enough to ignore poison capable of killing an elephant, and them being dozens of times faster than Brad makes dodging them impossible. Plus, Yor can completely null Brad's AP advantage (with Joy) and his superior stamina by hitting his pressure points
Brad could potentially win by spamming his
Firebombs and his
Joy empowered Fireballs since Yor lacks any fire resistance, but her acrobaticy and Instinctive Reaction make it far less likely, so Imma vote Yor
