Taking a look at it a different way the Difference between the Spit and the 109 tended to flow as different types came into service.

From a personal point of view this is how I see it.

BOB
I go for the Me109 as I prefer its weapons and also because by simply pushing the stick into a neg G the 109 has a very effective escape option that is very quick and very easy to do even by the rawest of recruits.

Me109 F2 vs Spit IIb
I go with the SPit as the weapons on the F2 were too light, something quickly resolved

Me109 F4 vs Spit V
For fighter vs fighter the Me109 had the edge, but it has to be said that the SPit was more flexible as a GA aircraft.

Spit IX ve Me109 G
The SPit IX had the advantage. It was a better HA fighter, the increased speeds of both aircraft also played into the hands of the SPit. Both were affected but the Spit was less impacted and finally the GA was becoming more important for both sides and the SPit was a better GA aircraft, Not a great one but better than the Me109.
Early 109G's had a serious problem with wing failures again resolved but its a factor.

Spit XIV vx 109 G
just magnified the difference

Summary
For the first half of the war the difference was close but the SPit was more flexible and this showed in the second half of the war. Finally in the often forgotten but vital PR role the difference was huge in the Spits favour.
