What was common and what was the difference between the feudal systems of Russia and the countries of Western Europe?

Perhaps the main difference between Western Europe and Kievan Rus was that Russia was able to bypass the slave system and immediately go over to the feudal order. Russia also lagged far behind in economic development, political development also lagged slightly behind the countries of Western Europe. Great backwardness was in terms of centralization, and in general the formation of the state, which is associated with the invasion of the Tatar-Mongols. If we talk about similar features, then here it was that there was a feudal lord, to whom the dependent peasants obeyed.
