Reasons: 1. Bounties: Jack, probably the weakest of the three calamities, has an 1 billion bounty, while Katakuri, the strongest SC, has about the same bounty. Spoiler Spoiler 2. Crews: Big Mom's crew seems more balanced overall. The strongest members of Jack's crew, Sheepshead and Ginrummy, are very weak (Sheepshead was one-shotted by Sanji). Scotch, an important Kaido's ally, is also very weak (he was defeated by Caribou). The only powerful Kaido's allies shown so far are X Drake and Apoo (but the Shogun of Wano should be strong too). Big Mom on the other hand has (or had) many powerful underlings and allies (Jinbe, Capone, Daifuku, Oven, Tamago, Pekoms...). Spoiler Spoiler Spoiler Spoiler -- EDIT -- 3. Numbers: Big Mom originally had four SCs. If the Yonko crews are even, then (1) her commanders are weaker; or (2) Kaido still has many unknown powerful underlings and allies. Spoiler I know that most of Kaido's crew and allies weren't shown, but 1/3 of his crew (except Jack) already looks like crap. So, what do you people think about it?
