He didn't blast the Inquisitor, and I don't remember him lifting a boulder.
The best TK feats he has are blasting Agent Kallus back and lifting a crate after some concentration. I think he's definitely more powerful than her, but I don't think he could do that stuff in a spur-of-the-moment lightsaber duel.
I'd say Scout takes this.
While Ezra is more powerful in the Force he typically has to concentrate to use his power. Most of his best feats (i.e. nailing Kallus with a push) were "heat of the moment" things in response to one of his friends being in danger, not something he can pull off at will.
His beast trick ability is very good but that won't help if there aren't any animals around.
Scout is far more skilled in both unarmed combat (extremely so) and lightsabre duelling, and Ezra's limited ability to draw on his greater Force power isn't enough to tip the balance.
