The Camel was on its way out by war's end as a fighter; it was too slow and not effective at high altitude.
However, with that being said, I think it's debatable whether the D. VII was the finest fighter of the war. The best Entente fighters at the time it entered service were the Spad XIII and the SE5a, both of which could outrun it (or run it down), thus allowing smart pilots to fight on their own terms. The Snipe, which was about as fast as the D. VII, but much more maneuverable, was about to enter service in numbers on the British end of things when the armistice came. Given the relative paucity of resources that Germany had access to, i.e. a/c engines, a/c quality wood, lubricant, etc., the German a/c industry probably would not have been able to deliver a fighter that could beat the Spad, the SE5a or the Snipe. Factor in the relative number of a/c that the German a/c industry could pump out compared to how many the Entente powers could produce in the same time frame, I still stand by my argument that in the game of technical oneupsmanship, the Germans lost. The D. VII gave them relative parity, not superiority but that parity would've probably vanished with time as things like the ropey Hissos on the Spads had their kinks worked out (thus allowing the XIII to fully replace the VII), the Snipe entering service in numbers came to fruition.
