It's not clear Russia is better at any of that, it's that Russia has land-based launch systems they can use in the war they started, whereas the US can't easily loan Ukraine an entire sea or air-launched system (particularly because the current logic still tends towards "no weapons which could hit Moscow easily).

Ukraine is not the United States military, and is not being armed with its full complement of weapons for very specific diplomatic reasons. Whereas Russia has been free to unload all it's conventional weapons as it sees fit.
