Yes .. passive torpedoes are good on surface ships. Even better than wakehomers. Wakehomers tends to follow even quite old wakes, thus attacking ships you didn't want to attack. Kilo Demo mission is nice example of that.
I didn't try them on subs, but I guess they'll work well especially against human. It won't ping so they won't be alerted that much and most humans only drops active CMs.
