Cutter have the cargo and distro for surface mining, the most profitable one. The best money maker for mining, but also some content like rescue of Human Pods. Not recommended for subsurface or even core miner.
Python is the best in his size, without downsides, and great multipurpose ship for passengers and trade, but outclassed by the Type-8 except for the best mining without compromise.
CobraMk4, the preorder bonus, its great with lot of modules, but only a bunch of players have this, and once you moved to medium ship, the ship lack a good niche.
Close, use as step for moving forward:
Type-8 have limited distro, a problem that will reduce mining speed,or increase your heat attracting RES pirates. Its good enough to use as step before going for the Cutter, without the problems of Type-9 low distro. Also not enough hardpoints for all form of mining in the same build. Close to be a great mining ship, but you always have some compromise.
All the other big ships have the distro but lack the cargo (Anaconda, Corvette), have the cargo but lack distro and/or convergence (Type-10 and Type-9), or are a downgrade over other ship (KraitMk2 loss a size6 slot from Python).
From here, CobraMk3 and AspX work great for his value, and can do lot of things. Even if other ship become better, you will enjoy the time with this ship when learning the game. Dolphin is a new addition with more cargo, Viper4 is close to Cobra, and Keelback is even better at 2x cobra price and fix the Type-6 lack of distro, but you are really close to AspX for a more rounded ship.
1 Useful stat... don't save a ship
Hauler, Type 6, Type 7 lack distro and hardpoints, pure cargo for LONG mining session with small lasers.
Orca and Krait Phantom are a downside over the KraitMk2, already under Python stats.
Viper3, Adder and the more expensive DBX are worse then Cobra3, the distro don't save the lack of cargo and other bad stats.
What are you doing?
This ones are starter or combat ships, that lack big modules for cargo, or have some of the optional slots restricted to military equipment. Anything else will be superior.
