Boy did your question open up a big can of worms. As you can see everyone has a favorite ship and opinions and arguments are as many as there are stars in the galaxy.
Theres more than enough ship configurations to do the job in a CZ. BUUUUT ship configuration depends solely on what a specific ships slots has to offer.
For example, an Anaconda has plenty of slots, big big gun slot availability. but it comes with a big downside, it doesn't turn (agile) very well. Turrets pretty much required for 360 or less degree of fire while you try and turn.
A krait mk 2 is more agile (medium), offers a nice amount of slots and hull tanks very nicely after you engineer (my personal choice of balance)
the lowest you can go,,,, the sidewinder, pretty quick (speed is more difficult to hit), and agile. Downside, Poor firepower, a couple of good hits and kaboom.
You have a great many bits of information to process to make your first choice. It will no doubt not be the last one.
Best wishes for your future success, Commander 07
