Yes, you are talking useless stuff that is unrelated to this. Mob being unable to find the boss has nothing to do with his ability to fight, which was shown plainly in season 2 as being very good. Mob not being able to defeat Mogami and the Boss in base has nothing to do with this fight, because they are higher tier than Mob unlike Ryuko.
But that's the thing, you are wrong. When it comes to psychic power, Mob learns absurdly quickly. Suzuki had his powers for much longer than Mob was even alive, despite this Mob was able to fight equally with him when both had the same level of power, only getting overpowered as Suzuki used more of his stockpiled power and, therefore, had more rawpower than Mob. Ryuko neither has much more raw power, nor does she have much experience either.
