He219 was underpowered, and no faster than other german fighters at the time. All the claims that it was "uber" or "super" were inflated hype and projections. Actual production models in combat had rather poor performance.
I'd much rather have the Me410 with a 6x20mm option, but also many other weapons options (8x20mm, 2x mk103, 2x mk108, 4x20mm, etc etc). Note this was also a day fighter, and since AH has little use for night fighters would probably be a better fit for the gameplay.
