Bearing Dilemma

The crank looks great and measures at the center of the book tolerances.
The rod and main bearings are in nice condition.
Bearing clearances measured by micrometer and by plastigauge are as follows:
Mains: 0.05/0.06mm
Rods: 0.05mm
Standard practice would be to replace the bearings, but I hear quite a few issues with aftermarket bearings and I wonder about the chances of winding up with worse clearances.
Here are a couple of photos of the bearings.
Can anyone identify the symbol?
