Grade my balls

Yo , i want to get some wheel hub bearings to upgrade my wheels . the wheels are putting in more miles and the factory bearings have got play in them. No way to thighten it out. So im shopping around , but became confused . i see grade 10 balls are lower that 3 and 5 . 5 seems to be the best but is a little bit more money than i want to put into non racing wheels . 3 seems to be the option i will choose . just wondering how they rank balls roundness and why thanks byeye ????
