IDEALLY BOTH THESE COMPANIES WOULD LOSE:  Texas jury hits Bambu Lab with $27.6M verdict in Stratasys patent fight — X1, P1, and A1 printers found to infringe prime tower and bed-leveling tech.

If we are forced to choose one or the other then Stratys delenda est. They are the very definition of everything that is wrong with the patent system. Invent something, use your government granted privileges to minimize the spread of the technology and dedicate your entire business model to ensuring it has as little impact as possible. Advancements in 3d printing technology are measured directly in stratys patent expirations. For example a few years ago when their heated chamber patent expired. In comparison the evil behavior of Bambu Labs is a rounding error.
