What state is winning the most at the moment between Russia and Ukraine?

I heard the Ukrainian people are putting up quite a fight. The problem with Ukraine is the continuing missile strikes against key areas and the 40-mile convoy getting ever closer to Kiev. For that matter, the problem with Russia (good for us) is that Poland donated fighter jets to Ukraine, according to this article: https://www.politico.com/news/2022/02/28/ukrainian-pilots-arrive-in-poland-to-pick-up-donated-fighter-jets-00012560

So, according to you, who will win in the war? Any thoughts?
