There are many reasons why the FockeWulf 190s were considered superior to the Bf109s.
For one thing, the Fw190, when it was introduced, was an ultra-modern fighter with about every sort of latest technology in aerodynamics, electronical systems and etc etc implemented. I believe the Fw190 was actually the only fighter that had the "Kommandogerat"(a primitive computer which was incorporated for automatic adjustment of fuel mixture, propeller pitch, and supercharger shifting all in one touch of the throttle lever) style of automatic controls during the time of its introduction. The Americans admitted the innovative usefulness of this technology and commented: "The 'Kommandogerat' or 'master control' units functioned well throughout testing and point up the need for further American development along the automatic control idea." When you look at the layouts of the cockpit, you will notice it has an amazingly "modern touch" when compared to the Bf109, which feels "vintage".
Another thing was, the flight characteristics were simple and easy to understand. Though it was prone to "snap roll" type of stalls, overall it was much easier to fly and control than the Bf109. Also, the control authority was excellent when in high speed maneuvering. There was no "signature quirks" - certain characteristic problems only that type of aircraft has.. for example, the P-51s being unstable with full fuel load, the 109s needing constant rudder input and etc.. - the 190 was as clear as it gets in flight.
The structural integrity was excellent, too. It was a tough and rigid fighter compared to the Bf109s which were usually considered 'fragile'. The landing gears were wide and sturdy. The engines were air-cooled radials and could sustain more damage than liquid-cooled engines on the 109s.
The fire power was about the most powerful amongst fighters when it was introduced. Formiddable armament of four 20mm cannons in the models after the A-1.
It also boasted incredible rate of roll, perhaps the best among all WWII fighters. Only a handfull few could outroll the 190s, and even that was limited to certain conditions(such as extreme high speeds. The boosted ailerons on the P-38 gives a better roll rate than the Fw190s in those speeds).
The only major weakness was that the low-speed maneuverability was severely lacking when compared to even Bf109s, much less a Spitfire. The overall turn rates were poor.
Also, after the introduction of Merlin-engined Spitfires in 1942, the Fw190s were hard pressed in most situations and the condition changed to "at least equal", which was previously "totally superior" when there were SpitVs around.
Compared to the Bf109, the climbing rates were generally inferior throughout most of the series, and it also lacked high alt performance and climb rates fell harshly once over 20000 feet.
....
The 109s are not really "BnZ" type of fighters. Its high speed performance and armament is severely limited for pure BnZ attacks. However, the 109s generally had excellent maneuverability and responded quickly to the pilots wishes. Also the acceleration was marvelous and the great climb rates enabled a pilot to climb away, when other fighters would dive and run. Therefore, the Bf109s have their own "hybrid" style of "semi-BnZ".
Generally, the 109 would dive in with alt advantage and speed in BnZ fashion, then when the enemy maneuvers away, it would track him down instead of going straight up like a P-51. It would tackle the enemy utilizing the built up speed advantage in various maneuvers in a turn fight, and when the advantage in speed and alt is about to dry up, it would disengage and climb away.
This sort of fighting capability greatly appealed to experienced pilots - delicate and dynamic. Compared with this, the tactics for the Fw190 was pretty 'straight-forward' and 'stale'. The 190 would excell in simple BnZ attacks, but it would not be able to engage the enemy in a dynamic manner the 109s can. Thus, experienced pilots were known to prefer the 109 over the new 190s.
....
In here, where we manage the throttle with a button and fly all day with maximum prop pitch and fuel mixture, the advantages of the technical marvel "kommandogerat" system does not shine out over all those planes which had manual control systems.
Flight characteristics of planes are always simple since many people fly with Combat Trim anyway. Landings are super easy, nobody crashes their 109 gears when they touch down at 190mph.
Firepower and durability? Couple of hispanos can damage things just as much as 4x20mms, and that couple can also knock of 190s in a quick slash - the way damage model is done, it neuters the advantages in 'rigidness' there.
Roll rates? Probably the best in AH, but the roll rates are neutralized too - connection and lag issues.
In conclusion, in AH, many of the delicate aspects which compelled people to think so high of the 190s are not modelled.
