Philly always had a weak defender out there for Atlanta to pick on and hunt specially after Danny got hurt. Seth, Korkmaz, Shake, Maxey are all bad defenders and they couldn't guard Collins with Tobias at all since Embiid needed to be on Capela. Trae wasn't efficient scoring but the others like Huerter, Collins, and Gallo killed Philly on mismatches and Trae did an amazing job setting them up
The Bucks don't really have a weak defender to pick on besides Forbes. Giannis, Brook, Tucker, Middleton, Holiday, Portis are all great defenders and the help defense and defensive system is better than what Philly runs too. So far game 2 was the best defensive performance (especially regarding Trae specifically) of the 9 games Milwaukee and Philly have had against Atlanta so far
That's just defense... Milwaukee also doesn't have to play 4 on 5 offensively with someone hiding from the ball every time he isn't getting a wide open dunk
