Depends on what you mean by "best".
Since you could say that the FW-190 was best due to how multirole it was, while also saying the Sea Fury was the best because it even today is used as a racing aicraft (and even has a confirmed jet kill, however it never served during WW2 but was developed during it).
But yeah, if i was to say overall best id probably pick FW-190 for its versatility, or early Spitfire due to its impact on the battle of britain despite having numerous flaws.
