As I'm still a noob myself, so I'll throw my recommendation in here.
Absolute first thing: Read the info on the trainers website and set up your views as it describes or get with a trainer in the Training Arena and let them help you set up your views. Regardless of what you fly, you cannot kill your enemy if you cannot see him. Well, eventually you may be able to, but you won't be able to right now...
Next thing is to turn the stall limiter off. I did not, and ended up having to relearn how to fly once I realized that everyone was right and it was seriously limiting my flying by having it on.
Now, to your actual question. In the beginning, new players almost always find themselves on the deck, slow and desperately trying to flat turn their way out of trouble.
...wait, that's still what I do
Anyway, for doing that, the best aircraft is really the A6M zero. While the A6M2 is a better turner, the A6M5 is a better platform and will out-turn anything else but an A6M2. Of course, people in bombers are going to look like they are out-turning you, but they are really just out-flying you. You won't be able to run away or run anyting down, but you really don't need to be running from fights anyway and treat anything that runs away from you as a victory. You can also climb like crazy, so try to think "up, Up, UP!" to yourself while you are fighting. Just don't go up with someone on your six...
After a while you will probably want to graduate to something that can take a little more damage, is a little faster and has better guns. That means the N1K2-J, Spitfire Mk VIII or Spitfire Mk IX among others. I would rank them Spit 8, Nikki, Spit 9, but that is only my opinion. The 109's are good, but require constant throttle work to be effective. The P-38 is good, but requires a smooth hand on the controls, constant flap work and good energy conservation skills. Really, the key is to fly something that you enjoy and stick with it for a while. Go to the training arena and try out several planes. Or all the planes. You can have all the planes you want for free, so there is no reason not to experiment.
One last additional piece of advice that you did not ask for is to completely ignore your score. Other than your gunnery hit percentage, the rest is really meaningless. Go have fun.
