Default Precision 7675 or Turbonetics 7875?

I'm doing a Lm7 5.3 shooting for about 700-800 whp, and I ordered a precision 7675 (cast wheel .81ar journal bearing) and it turns out it'll be on back order for another month or so at least. The shop I ordered from offered to let me switch to the turbonetics 7875 (.96ar cast wheel ball bearing). I'm not needing the turbo right away, but I'm wondering if the turbonetics would be better?

The car itself is an 02 fbody, with a 4l80e trans which will get a custom spec'd converter. Probably weighing around #3700 when done, stock bottom end 5.3 with stock 241 heads, ls9 headgaskets headstuds, will do a custom cam if needed, etc. Basically the standard turbo 5.3 build.

I'm just wondering if one would be advantageous over the other? I originally had the 7675 spec'd for use with an M6 trans but have since decided to go with the auto trans. I may opt to change to a .96 ar on the Precision if thats the better unit of the two. Does anybody have any back to back testing with these two turbo's?

Well.... for $1500 ish, I went with the Turbonetics billet 7575 ball bearing.

Hard to beat the bang for the buck. Had a turbonetics t72 before, but close to maxing it....
