Well, for me a KB is a great mission ship. 32-64 tons is more than enough tons for mission based adventure. Fully augmented and engineered I can spend as much time as I want in a CZ or REZ area. With the fighter and a good pilot I can choose between what kind of fighting I want to do. It's even a decent exploration ship with a maxed out FSD (smaller size means easier to land in rougher ground) - having a figher and SRV for exploration means more fun options depending on terrain.
