Considering how it ended I think it can only be better.
True in a way. The political system would most likely not be as dramatically shaked that forces like Fascism and Communism would have gained such a shot at power without a long war. And given the great many conflicts after the Great War maybe a more jingoistic victorious Entante would not have made such a difference tro the situation in regards to new conflicts and wars.
Probably more like the earlier Franco Prussian war but in reverse in the west at least. It also means the Ottoman empire would not have participated. So the sick man of Europe keeps dithering. God knows what would have happened to Austro-Hungary and Russia though.
True that, Germany would probably have come easier from it but its probably impossible to say how Germany would have taken a defeat like that. But hopefully it would have been better than how they took the defeat in the actual Great War.
Austria-Hungary was done for. The Russians planned to cut huge pieces away from it, and would have looked with glee at the total implosion of Habsburg power in the rump that would be left after Serbs, Italians and Romanians were done taking their share.
My big question is, would the Romanians have gained any wins since they only entered the war in mid-1916, if the war ended in early 1915? They might naturally have entered earlier in order to wins some scraps for themselves. Same with Italy which only entered in May 1915. Would they have been in time to take part in the spoils?
What about the peace terms for Germany? Alsace Lorraine is a given but would the Entente still dismantle the German colonial empire and demand large sums if the war was shorter and less bloody? Russia probably wouldn't want an independent Polish state so the question is if they would take the territories Germany historically lost to Poland for themselves.
I would assume that the French and British would have wanted to keep their colonial domination and if we look at it, it looks to me like the only significant European colonial power which wasn't at war with Belgium was Holland, so the western parts of the Entante would most likely have loved divided the Germnan colonies between each other.
As I think was mentioned I don't think that the Russians were really interested in winning lands from Germany on a big scale. I think that more likely they would have focused on the Balkans with a restored prestige of the tsar from a victorious war, they may have re-opened their ambitions in the Far East in a longer perspective to vie with the Japanese over that sphere.
But then again, Nicholaus II, not perhpas being the shrewdest of men may have fallen for the temptation to get German lands on a large scale and so get even more angry minorities into the Russian Empire. This time with an industrial power house right on Russia's border which would be sympathetic to these Germans complaints about being in the Russian Empire. But then again, maybe it would have worked out just fine like with the Baltic Germans in the Russian Empire.
There would be much fewer war poems for students to be forcibly exposed to at school.
I don't feel that would have been a win. I like poetry.

More seriously: I struggle to imagine an early peace scenario that does not result in a German victory.
Really? Germany gambled on a quick win and didn't have the power to fight a world war against most of the world. Not to mention that it was under blockade and all. I really don't see it as impossible that for example a Russian victory in Eastern Prussia instead of Tannenberg could have caused a total collapse early on in combination with no scientific advances to for example provide Germany with synthetic alternatives to materials and other stuff they couldn't import any longer, like leading to a lack of fertilizers to keep the German population alive and a ammonia to produce munitions.
