Read this please it took long time. and i know he meant early mustangs

I destroy propaganda
Jenwuf Now im British and id love to just say that the spitfire was a flawless machine, but the P-51 (specifically P-51B ) was perhaps one of the greatest fighters of WW2 for the important role it played.
it's the fighter not it's role. u might as well say bf 109e because it meet polish and French paper airplanes.
Jenwuf At the altitudes that the bombers flew, the fighter was superior to almost anything that Germany threw at it due to the fact that of course, they outfitted the 109's and 190's to hunt bombers with larger heavier guns, making them slower and overall unable to counter the fighters as well as normal.
If you want to count the scenario, it doesn't matter because the p-51 had to fly at the same altitude as the bombers which mean the germans could ALWAYS have an energy advantage and thats where their planes shine. the discussion specifies best fighter not best fighter escort. Did the b version have Merlin? And you can’t compare to the only nation it faced against. It was a great strategic plane but if you count the senario the German fighter could just outclimb the and dive down. Spitfire and yaks where very easy to fly. F6F, 109, Spitfire and the other top planes dominated the sky at there time maybe except another plan over it.
Jenwuf Oh, and that is ignoring the fact that it served in numerous countries for a long time, and even now is a civil aircraft.
Although Id prefer the spitfire in a dogfight, you must remember the design's purpose.
so did yaks, 109's, spits...
Jenwuf But regardless, with a lot of these you seem to be looking at it from a "best scenario" perspective.
Now sure, a lot of aircraft could outclimb or out-turn something, but then you remember that stuff like visibility and tactics make these aircraft very different in a fight.
you must compare the time period. The p-51 counter parts during it's time usually as had good visibility. And if you far from an enemy you can start climbing then turn back and BnZ them or energy fight them easily.
Jenwuf (also, real life is not like war thunder or any other game, these aircraft often do not like pulling up quickly or making very sudden movements, in reality its very likely a pilot in a quick-turning plane might not turn as fast as he could for fear of entering a stall or spin. This also means ammunition loads are important, so twin engine heavy fighters have a HUGE advantage there.
Oh, and stuff like how easy the aircraft is to fly from a controls perspective also matters.
I do play WT. But i don't base my facts on it even tho it may look so as WT is very accurate. You also forgot g-forces which is underwhelming in WT. AND PLANES HAVE LIMITED AMMO LOAD IN WT. you can't say it's inaccurate until you know about it. I've watched plenty of documentaries and I've never heard a pilot say, "I didn't want to turn" or "i was afraid of turning". Ammo is important but firepower is to. You'll need way more ammo for machine guns as you burn them faster and need more rounds to down a plane. I agree the early cannon spits and french planes had little ammo for their cannons. and if you have an altitude over a twin engine you practically won.
Let's compare it to another fighter:
Spitfire mk XIVe should be directly comparable

Engine power
Acceleration: Spitfire wins with quite a difference
Top speed: very even but on both ideal altitudes the spitfire wins with about 20km/h
climb rate: This is extremely important m8. Spit wins
Energy retention: I could't find any confirmation but i believe the P-51 win as it has smaller wing surface but if you count the spits acceleration which is constantly pushing it forward im not sure.
Firepower
Guns: The spitfire is more heavily armed with two 20mm and four 7's. The mustang has 6 50cals. Pathetic
Ammo: The P-51d has almost UNLIMITED AMMO. Spitfires cannons 120 rounds per cannons.
Maneuverability
Turning: Spitfire by a kilometer (metric system>imperial system)
Roll: Mustang smaller wing give better roll
Visibility: draw
fuel: Mustang can have more oil in it.
You saw the end result. The spitfire dominates all the main fields that not even the best spit.
