It depends on what you are doing. I'm impressed that you are able to afford these ships after only a week of playing, great job! Always keep enough spare cash for a rebuy. I assume you have been mining to get that many credits, so I'll give you recommendations based on that. The Python is my favourite ship for Void Opal Mining, as it is fast and has decent cargo. Also, it can land on medium sized landing pads at Outposts, which often have better sell prices for Opals, and large ships such as the Type 9 and Anaconda cannot land on. The Type 9, on the other hand, is a lot lot slower than the Python, which makes it unusable for Void Opal Mining efficiently. Instead, the Type 9 is one of the best ships in the game for Painite mining at an overlapping painite hotspot, due to its huge cargo. Dual painite mining will take longer than void opal mining in a Python, but will have much greater rewards. Also, the Python is a capable combat ship, but the Type 9 can take a fighter bay. If you're looking for a good combat ship though, I would go with the Krait MKII, it has one less size 6 optional slot than the Python, but can take a fighter bay, has better manoeuvrability and speed, and has better hardpoint placement. You can also use the Krait for opal mining, but the Python does beat it in that field. I hope you can make good use of this info. Fly safe CMDR!
