performance in this diagram for the Dora is without overboosting
Don't know what you think you've seen, but the diagram is definitely with overboost.

Supposedly the Soviets tested it at max nominal. Not the full 1.8 with whatever device they used, I believe MW50 on the Dora

though we can go ahead and get a full diagram for the dora as well:
(again without MW-50)
You can see that it gets closer to La-7 at nominal power, even slightly outclimbs the La-7 at the lowest few hundred m of altitude.

but that was a test prototype
final machine performed more like this:



And with MW-50 the difference at low altitude is miniscule, with advantage for La-7, past like 2 km, the Dora takes it ove and gains more and more advantage as you climb.

As for Ta-152H-1, yes, it is supposed to fly like a pig, at an altitude of less than 9 km. Blame the glider-like wings :))


So no, instead of thinking that this is a case of someone liking or hating something, it's a case of inaccurate modelling based on very limited data. Just for comparison, the Dora in DCS very much is a pig ;) compared to the 109K-4 and good old Spitfire mk.IX at least.

But hey, things can always be improved, as was already mentioned. Just don't fall into the BEST FIGHTER OF THE WAR pit, that many have found their way into.

Here also the MW-50 test:

The high aspect ratio wings of the 152H are supposed to cause a certain amount of unwanted drag at low altitude, and they are supposed to cause a much worse roll rate compared to a "normal" Dora.
But they are not supposed to make the 152H fly like a pig.
Not at all.
No reason for such thing.
And the few available reports of pilots fighting in a 152H - and these fights where reports are available all took place right on the deck - indicate the exact opposite to a plane "flying like a pig".
The pilots deemed the 152H their life saver.

Perhaps we need to mod a flying pig (even a Franken-Pig might be good enough) so we can compare it to the 152H.
