Base ASW attack power for Yuubari and Isuzu is:

Original ASW / 5, rounded down) + Equipment ASW  × 2 + 25

which puts Yuubari at 38 + equipment x 2 and Isuzu at 43 + equipment x 2

The difference of 5 is easily countered by an additional sonar which gives 20.

So in the end, if you go full ASW Yuubari wins always.

And if you think the formula is wrong, someone tested Isuzu against Yuubari and found out that Yuubari does more damage against subs. That's where the formula comes from.
