Question about Bf 109K-4

[Flammenwerfer]

Hi!

I have some questions about this late german fighter.

First, I heard a lot of opinions that Bf 109K-4 was not good enough comparing with Fw 190D-9 or H-1, both well known as the best German propeller fighters at the end of WWII. Is that really true?

Second, I'm interested with comparing the number of Bf 109K and Fw 190D9/Ta 152H1 at their service in Luftwaffe. I hope the number of victories of each aircraft and the number of serving planes will give me good view of true effectiveness these fighters.

Third, what was the production cost of one Bf 109K-4, Fw 190D-9 and Ta 152H-1. If it's possible to find, I want to know.

Finally, what was true value of Bf 109K-4. Was it a scrap with powerful engine (I heard such as opinion) or was it a good fighter?

Thanks
