YMMV: I liked Hail Mary just as much, if not more then, The Martian. It had the same "solo dude using science and cleverness to solve an impossible problem" with a massively more ambitious plot. Also, the plot twists in Hail Mary are very well delivered. The book ends up being completely different then you're expecting when you go into it.
