The Ta 152 has superb high-altitude performance, great E retention, and an awesome gun package. Kinda like the Spitfire Mk XIV, except it's faster above 29K. It doesn't have as good a turn radius or climb rate though, even at this alt, though, but that doesn't matter because if you have speed you can dominate the fight, right?

On the 109's views-- sure, you can say the Bf 109E, F, and G-2 have bad views. Maybe even the G-6. But by the G-14, with it's Erla Haube, the views are almost as good as a bubble-canopy plane. Better than the 190 at least, IMO, since the two bars it actually has are in a much more convenient place than the 190's one.
It's dive is not great, but far from 'dangerous'! In fact, I usually use the dive against Spitfires. If you can find the 'K' key, or use manual trim (as I do), you have to worry more about blackout than the responsiveness of the elevators. If you're going to call any dive 'dangerous', it would be the Spitfires, whose wings rip off at high speeds and high G-loads!
On top of all of that, though I would agree that the Hispano is a better weapon than the Mk108, it's effectiveness is drastically reduced when you're fighting the Griffon.
