Yes, lower grade is better. The grade number equates to tolerance and smaller tolerance is better.
Btw, don't mix batches, even from the same supplier. Uniformity of size between bearings is much more critical than absolute size. Ball bearings are spec'd for close uniformity within the same batch, and different batches may be significantly different in size.
