Rear bearings, green vs timken

I am sure this has been brought up before. What is the better bearing and why? I am rebuilding a 67 b-body 8 3/4 for my duster which will be daily driven. I drive the car hard and play even harder. I will be running a 741 case with sure grip and currently running factory 10" drum brakes. If it matters, the car has a mild 340 with built 904. I plan to run 15" wheels and SS springs with rear sway bar.

Thanks in advance for the thoughts...
