An ARC-170 fighter. Can go toe-to-toe with an X-wing class.
"During the Galactic Civil War, ARC-170s could be found in both Imperial and Rebel fleets, where they were considered elite craft."
A fine ship, but you couldn't capture and transfer bounties from their ship to yours..........or even have a place for prisoners in one could you? Not without serious modifications, at least.
Personally I'd go with the StarViper. It's a serious gunslinger and great dogfighter, yet still has a little room for prisoners, supplies, and sleeping quarters. Not as much as Slave I for sure, but more then an X-Wing or Arc-170 type fighter.
Or, if you want to bring partners into the mix, use 1 or 2 fighters working with a larger craft like a modified transport/freightor. Then you have the kill/capture capabilities the fighters give you with plenty of supplies and prisoner space for long hunts
