These teams split their six regular season games against one another so it seems that they are pretty evenly matched. Charlie Morton has an 8-3 record with a 3.06 ERA in their 15 road games this season, but was 1-2 with a 4.17 ERA in day starts while Corbin Burnes is 7-1 with a 2.50 ERA in 13 games since the All-Star break.
Corbin Burnes finished with a league-best 2.43 ERA in 28 starts.
Burnes also has made six playoff appearances and has a 2.00 ERA.

These games are expected to be close but I trust the Milwaukee bullpen to get big outs compared to Atlanta's. All in all, go with the Milwaukee Brewers to win at home for Game 1 and have the momentum.
