After the Delta I bought a Gladius because the Delta had no effective shields. At first I could survive much longer, but couldn't do much damage because the Gladius was much too agile and fast to get a good aim.Rented a Warden for a week and ended up buying a Sabre instead....and then I bought a Warden because I'm a sucker for Aegis design.
Cosmetically the ship is beautiful, functionally it's a flying brick. The damage it could deal unfortunately is gimped by how horrible it is to fly.
Not trying to talk you out of it all, just giving my feedback as others have.
Zoom improved my aim allot. Strafe gives me more control over firing distance, so longer good aim.
In the beginning I would mount 3 fixed CF-117. After the Avenger I got used to a ballistic in the nose. Perfect to finish off when close enough.
Conclusion: a fighter isn't by definition a good or a bad fighter. A fighter like a pilot has skills. The skills of a fighter must match the skills of a pilot. The fighter isn't flexible, a pilot is, so it's up to the pilot to make his skills match to the fighters skills. The pilot makes a good or a bad fighter.
