Here are three assassination hypotheticals for you:
1. You can either prevent Franz Ferdinand's assassination or assassinate Vladimir Lenin. Which one would you choose? I'd personally choose the first option here since that way, I would get to prevent both Bolshevism in Russia and the Armenian Genocide in the Ottoman Empire, but if it wasn't for the Ottoman Empire's extremely massive human rights abuses during WWI, then I'd be more undecided about this since I really do like a lot of the territorial changes that World War I produced. I suppose that it might depend on whether these territorial changes were eventually going to happen anyway or not.
2. You can either assassinate Lenin or assassinate Hitler. Which one would you choose? I'd choose Lenin since it's unclear that there would ever actually be a Nazi Germany without the USSR and in any case, it would be easier to form an anti-Nazi coalition without the USSR's existence, thus making the Fall of France much less likely even in the event that World War II still does eventually occur with a Nazi Germany.
3. You can either assassinate Lenin or assassinate Stalin. Which one would you choose? I'd choose Lenin since Lenin was much more crucial for the creation of the USSR than Stalin was and since the USSR was already becoming a totalitarian nightmare even before Stalin seized absolute power, with even illegal emigration from the USSR becoming nearly impossible by the end of the 1920s. So, I'd prefer the USSR not to exist at all since I don't actually believe that it can evolve into a milder form for decades afterwards.
