That's relatively simple. Based on BR, I would say the following could be expected:
Heyward: 1 year, 6 WAR, $7.8 million due
Upton: 1 year, 3 WAR, $14.5 million due
Kimbrel: 4 years, 10 WAR, $46.5 million due
Simmons: 5 years, 20 WAR, $53 million due
Sale: 3 years, 15-20 WAR, $38 million due
Eaton: 5 years, 20-25 WAR, $29 million due
So in raw numbers, you're looking at a projection from the Braves' side of about 39 WAR at a cost of $121.8 million. On the White Sox' side, you're looking at a projection of about 35-45 WAR at a cost of $67 million.
So in raw numbers, the White Sox were looking at quite a bit more value they were trading; roughly the same value in wins at just over half the cost. And if you consider that it's likely more valuable to get the same WAR out of fewer players, the White Sox were working with even more value there.
Alex Wood was also worth about 10 expected WAR at time of his deal
