Academics rate post-war PMs

I don't often write about polls of specialist groups, unlike polls of the general public (relevant because they are the people who vote in elections, and easily defined because it is everyone entitled to vote) they are often rather arbitary and hazily defined samples. However, since it's quite a fun subject and we are into the August silly season, there is a straw poll of 100 academics in the fields of politics and history here, ranking the post war PMs. In order from best to worst, they come out as

1. Attlee 2. Thatcher 3. Blair 4. Macmillan 5. Wilson 6. Churchill 7. Callaghan 8. Major 9. Heath 10. Brown 11. Alec Douglas-Home 12. Eden

Doesn't mean anything, but feel free to discuss. Personally, for a ranking of post-1945 Prime Ministers I think it rather flattering to Churchill, who was manifestly unfit for the role of PM during his 1951-55 stint, and probably unfair to Heath, who despite the disasters of his premiership did at least have the major achievement of British entry into the EEC to show for his years in power (you might not think it a particularly good thing to have achieved, but at least he achieved a major policy aim).

(And please, try to discuss in it a detached way rather than use it as an excuse to be rude about recent incumbents from the other side. It's what PM's achieved in their time in office, not whether they were evil socialists/capitalists (delete as applicable) who brought the country to its knees, etc.)
