I don’t know how specifically it compares but I know that self-propelled 155mm howitzers do dramatically better avoiding counter battery fire than towed artillery.
I don’t doubt that they’re much better, but they’re also specialised vehicles as big and heavy as tanks. If you are trying to equip a massive mobilised force, you’re going to have a much harder time giving them enough of those vs giving them enough lighter guns that their trucks can tow
Surely a gun that can be easily towed without specialised vehicles is a great fit for an environment with severe counter-battery fire?
