While Yuiga loses 1 out of 4 to Osamu in a face to face gunfight despite having double his trion and being a gunner, Wakamura was straight up raped by the Four eyes under much more favorable conditions.
If we go by stats alone Jackson's are higher on all accounts, attack/defense/tron/skill/tactics/mobility all are 1 to 3 points higher than Yuiga. If we compare the trigger layouts we will find something very interesting
Double asteroid handguns for Yuiga, chameleon, bagworm, double shield.
Assault rifle asteroid & hound for Wakmura, chameleon, bagworm, double shield.
Yuiga & Wakamura run basically the same loadout with Jackson's hound being the main difference, usually handguns have lower range, however both of them have a range of 4, so no advantages here. Hound should be great against a low skill enemy but Wakamura swapping a trigger is a bit too much to expect from him at this stage.
As a pure 1 on 1 before any story even'ts I'd say Wakamura is well favored to win an average 10 round, he just has more trion and his gunner basics were nailed down by the Inukai, meanwhile Yuiga is most likely just winging it with his double handguns because it looks cool.
Now if we take Yuiga after 200 battles, I'd say he is favored to win a 10 round, Osamu doesn't fight fair, he will look for weakness and abuse it, for that reason he would make a great sparring partner for someone looking to Improve.
Finally with Wakamura after Canadian consulting, I'd say its back to him being favored. Wakamura has superior stats, superior training and better weapon, the main issue is his empty head refusing to tick. With that mostly solved he should naturally realize that he has the edge in a direct firefight, calmly swap to hound and shoot Yuiga full of holes.
