Retreading the same tired line. Again no one is disputing that Britain gained from the delay created by Munich, the point other posters here have been trying to get you to understand is that Germany gained far more.
It is interesting that Tooze in his book The Wages of Destruction argues that one of the reasons Germany went to war in Serpt. 1, 1939 was because it was becoming clear that Germany was encountering formidable economic, , structural and resource barriers to it's military build up and that after the benefits of Munich were exhausted, Germany's military position in relation to Britain and France would deteriorate from early 1940 on. This was because in the wake of the occupation of Prague in March 1939, France and Britain made efforts to accelerate rearmament. (To a large extent forced on reluctant governments by an irate, angry population.)
In other words things would never be has good for Germany militarily after the fall of 1939 to it would be best to strike then.
So yeah Germany benefited more from Munich and its fallout than France or Britain, certainly militarily, but with the greater resources, fiscal etc., of France and Britain that advantage would start to disappear from the start of 1940, so it would be best to strike while the iron was hot.
Tooze also argues that the idea that Hitler expected France and England not to declare war if he invaded Poland is wrong. Instead Hitler expected war with the Western powers and indeed hoped for it.
does this have to do with appeasement??
