As long as you're keeping it to low tiers,
the Hurricane and Hurricane II are both great planes for their tiers (very low), they have mediocre flying charactaristics but their armament is very impressive. 8 and 12 .30mm machineguns respectively will take down anything that ends up on the wrong side of your plane in mere seconds.
Then there are the Spitfire I and the Spitfire IIb a few tiers above, which are absolutely amazing. I honestly can't say how much speed they lose while turning, but they outturn almost everything they encounter and they easily finish off enemies with their impressive armament. The mk1 has 8 machine guns that spray so much bullets you'll always hit the pilot eventually, and the mk2 has 20mm cannons that tear everything on that tier to pieces. And you'll always be able to use the armament, because almost nothing can shake a Spitfire off its tail.
This tier (cap at 8 or something) even comes with the Beaufighter MkX (I think, anyways it's the second one in the tree) as a bonus which is one of the best heavy fighters of its tier. 4x20mm cannon and 6x .50cal blows everything in half with a few short bursts, and it even comes with rockets too.
IMO, it's much more fun to stay at this tier level than to advance to tier 10-18 where the game becomes more of a oneshot-fest.
