I've bought and engineered pretty much every ship that I have every interest in flying but the one I always wind up going back to is the AspX. There's nothing particularly special about it. I don't like the way it looks or sounds and it isn't great in a fight. It isn't even particularly fun to fly. It's almost always the best tool for the job, however. I've had it for years and it's made more money/collected more materials for me than any other ship. There have been many times when I've been halfway through loading out my python or anaconda, only to sigh and jump back into the Asp because it's already everything that I need and it can do what it does in less jumps than anything else.
