I think most of the power comes from the Fury's absurd tankiness. Its Flux capacity and probably Armor are imo too high.
And a large part of it is also the Shield Conversion - Front hullmod, wich is frankly overpowered. Does it really need to give you Extended Shields, Accelerated Shields AND Stabilized Shields all wrapped in one cheap hullmod, with little drawback ?
I'd much rather have a Fury for 15 DP thats a scaled up Shrike with a focus on speed and offensive than a scaled down Aurora for 20 DP with focus on relative tankiness.
The later doesn't really fit the lore of the ship.
And there is a tanky high-tech ship with 360° shields in the 20 DP range already with the Apogee.
