I'm considering buying one of these two mounts (to pair with a SkyWatcher BDED100), but I can't decide which one. I know HEQ5 Pro is a well tested design and lots of people are very happy with it, but I've also heard that the Advanced-VX mount is a newer design than the HEQ5 Pro and the motors have improved tracking performance and provide more power to overcome minor load imbalances. The updated industrial design of the Advanced-VX also offers more rigidity, less flexure, and improved aesthetics. So, what are everyone's thoughts and experiences with these two mounts?
