I wold say that is advertising hype.
Good industry bearings are just that, good bearings.
I use:
6307 C3 - you will find the bearing under this number regardless of maker. Both sides are the same.
C3 denotes the tolerance of the ball race; 1 very tight to 4 very loose, C3 is normally used for such purposes, C4 very often for 2-stroke racing cranks.
I use this bearing on the flywheel side but on the drive side I use:
NU 307 ECJ
a roller bearing with loose inside ring. this bearing is much used in racing engines because it can take a much higher load and assembly and disassembly is much easier, too; the ring goes in after the crankcase is assembled.
It is, however almost twice as expensive.
I use
SKF bearings myself.
