It's complete shit. In order to use a ground attack plane you have to have complete air superiority. Since when have you ever seen that happen in War Thunder? Never. It can't even outrun a BF109G let alone any jet it's put up against. You're literally a sitting duck that has to rely on not being seen and that only works in a Monty Python skit.
Only if they want to engage in a dog fight, otherwise it's a missile. No one wins against a missile most times unless you can get lost in the ground scatter.
But seriously the turning ability alone would fuck up a gun engagement.
