In the real world, you can't compare the 101st Airborne to SEAL Team Six because they're two very different units.
Yeah, it's like comparing A-Bridge-Too-Far
. A-Bridge-Too-Far ALWAYS wins in the end, it's just too epic.
In reality, both uses the same concept, Sami's insane gamebreaking capture rate modifier allows her to captures over 6900 + 96 properties near the combat area, which lead to her have more funds thus more units. Sensei's even more gamebreaking COP that lead to the ritual harakiri of several IS employers, gives him free units. So in the end they all uses the number game to win. You said that you can't compare the 2, while this has an element of truth to it when they're pitted together, as the number game changed to Sensei's favor, while the "efficiency" lend to Sami's favor. The comparison is like when people used to think that there are 2 types of fighter planes called "boom-and-zoom" and "turn-and-burn" (boom and zooms can go very fast but can't turn very good, as such they attack by going in, swoop down the enemy, and go back to hide in the bushes. While turn and burn can't go fast, but can turn very well, so they'll try to get the enemy in a turning battle and shoot them down from the behind), and does not realized that they only have different band of energy and nothing else. (airspeed and altitude combined are called energy, this phrase means that they both manipulates their overall energy in such a way that they're still equal in energy to each other despite the differences. Sorry for the high usage of aerial philosophies and terminologies, I just can't help it being a avid WW2 simmer
) Which means that even though "boom and zoom" can't turn as fast as "turn and burn", they still retains a huge amount of speed in a turn to get very close to a "turn and burn". Like wise, the high turn rate and great speed conservation abilities of "turn and burns" allow them to out runs even the fastest of "boom and zooms" at times. Which means that they're pretty much equal, a good example of this is a battle between the Japanese A6M Zero and the F4F/F6F Wild/Hellcat.
Both CO's can win the fight either by numbers or firepower, Sami's wall-hacking, capture rate modifying train wreak could capture more properties than Sensei given the right map, which not only gives her more funds but also DENYING him of cities he could capture. In other words he'll get less units by COPing. While Sensei could still win the firepower game with a brain damaging amount of units, as 2 110/100 infantries could still be better than 1 120/100 infantry, that and the fact that he wouldn't need to create infs that often, he could make more armored units. The only thing that matters in the end of the day is army size and efficiency. And as Sensei got nearly triple the army size and have very little loss in firepower, he'd be all over her in 16 consecutive seconds.
