You have to be able to detect a submarine to fire on it and the US is a long way ahead of Russia when it comes to both quiet submarines and passive towed arrays.
In fact the original argument for the super-cavitating torpedo was one based on the premise of killing a submarine that already fired on you that you hadn't detected until it fired on you.
Russia has some showy tech (as you mentioned) but they lack in areas the US was ahead of them in decades ago.
In terms of technology there are other countries with more sophisticated defence capabilties where I am from is one (the UK) is one, much of the technology the Russians export is things they did under the USSR (which definitely was #2 in terms of military tech at that point).
When you get down to it though modern war is force projection and logistics and there no one touches the Americans.
