Has anyone compared these two Pro systems in a medium sized venue?
Hey jdpuentejr and welcome to the Bose Pro-Portable community!
While there are currently no videos that specifically address your inquiry through demonstration, I encourage you to checkout this video that talks about venue spaces (among many other variables) and covers a "Throw Over Distance" comparison between the Pro 8, Pro 16 and Pro 32 Systems.

Hope this helps!
