I read the 190 pdf when you posted it and it doesn't back up your point at all. The 190 was a great fighter, my favourite looking WWII aircraft, and it was superior to the Spit Mk V, we all know that. But the Spit mkV was out before the 190, and as soon as the RAF met the 190 in the air they stuck a bigger engine in the Spit (giving the mk IX) which was immediately superior to the 190.
According to
http://www.wwiiaircraftperformance.o...0/fw190a5.html
the mk IX (1942) was as fast as the 190 A5 (1943), and easily outclimbed and out manouevered it (despite the 190s superior roll rate).
So your evidence of the Spitfire taking forever to build up speed, is a pdf that says nothing of the sort.
As with the 109, the 190 had other things going for it, like its great roll rate, impressive firepower, good dive speed etc. If you were at altitude in a 190, this meant you had a good chance of rolling and diving away when in trouble.
Later versions of the 190 continued to get faster, but the pdf you linked to doesn't show direct comparison with the Spitfire (he says the D9 was one of his favourites, along with the Spit XIV, P51D IV etc), but instead points out that the Germans had a shortage of pilots and fuel.
