xx1 vs x01 bcd differences

[goodluck Phil danger]

I've read that the smaller xxi spider and chainrings are more expensive to produce, thus the larger bcd on x01.

The only negative of this larger bcd the mention, is that you will not be able to run a front chainring smaller than 30.

 

Are there any other notable factors to take into account?

You hit the nail on the head. Cheaper to run XO1 although XX1 has bigger bling value, but hey anyone ridding whatever 1x10/11 automatically moves up in the pack no matter what they ride
