Attention settings using Face ID on iPhone XS

Forum
iOS and iPadOS

Hello,
I was wondering which setting you guys prefer to use when using Face ID attention. I have tried both, and find it when I'm trying to purchase things from the iTunes store, I think you have trouble getting it recognizing my face when I have the attention settings turn to on. I know that is less secure to turn them off, but since it is usually off by the fall on voiceover is on and you're setting up Face ID, this still seems to be a viable option.
Have any of you found either one more useful? Thanks for your information and help.
