Beyond a doubt, I think that's an enormous improvement. Imagine Trump trying to plan, coordinate, and execute this response across the federal government, NATO, the EU, and countries worldwide.
However, my (vague, inexpert) impression goes back long before Trump. Obama, etc. seemed always a day late and a dollar short. Remember Obama's response to Russian interference in our elections? Not the actions (which I doubt many remember), but the words? Neither do I.
Apparently, "integrated deterrence" is a DoD concept for integrating all (or much) of the executive branch in objectives - sanctions, information operations, etc. Perhaps that's what we saw in regard to Russia and Ukraine. According to one Congressperson, it's the first time it was applied to a real situation.
