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...
I am in the process of replacing mine as well. After some research, I am convinced the "Green Bearings" are the way to go. No internal seals to worry about and no preload adjustment. Simple easy and affordable. I ordered mine from Mancini $85.00 bucks plus the cost to have them pressed on to the axles by a machine shop.
