I have had the opportunity to work with both the original Champion and the G12. I can not speak to the genetic stability problem as I have not had that issue arise, but I have witnessed a distinct difference in the rooting capability of the G12 as well as its endurance.
Where my course has Champion greens, my experience with the G-12 comes from helping rescue a course after an episode of dereliction of duty by an exiting superintendent. The G-12 greens were only about 6 months old at the time and had been seriously deprived of water as well as other needed care for an extended period. By the time I was brought on site the turf was seriously weak and degraded but what amazed me is that there was still substantial viable root mass underneath and the roots were uniformly deep (excepting a few areas where high nematode counts were later found). It took awhile but the majority of the greens surface (there was some sodding required but a lot of it had to do with poor grow in and nematode pressure) recovered and is now in excellent condition.
I tell this story to illustrate that I do not think that it is merely the original Champion repackaged. I can see distinct differences and advantages from the G-12. As to weather it is better than TifEagle, I will let you guys figure that out!
