If I can suggest another plus to the Hurricane compared to the Spitfire, it is that it was more easily repaired and it had a much higher sortie rate than the Spitfire.
We would have been is serious trouble without the Hurricane. As getting planes in the air that could fight effectively, was almost more important than performance. There is no doubt that the 109 was better than the Hurricane, but it wasn't a sitting duck either and the highest scoring squadron was a Hurricane squadron.
I am sure that many a German pilot couldn't make the most of his advantage due to the lack of fuel, which was a significant factor in the battle.
Another factor is the ease of which it could be flown by the rookie pilot, very much a factor in the BOB and here again the Hurricane would be the best.
With all this in mind and considering that the point of the thread is which was the best plane in the BOB, then my vote is for the Hurricane.
If it was which is the better fighter 109, Spitfire and Hurricane then it wouldn't be. For the BOB however it was its
