$129 is pretty cheap nowadays, you can get a Google Home for that price.
GoPros are a convenient, high-quality, expandable memory camera that creates a regular video file as big as the storage space available that you can use however you want.
Spectacles are a convenient, unknown quality camera creating a ten-second video that requires smartphone interaction, is designed to be on your face, and is tied to one specific (albeit popular) platform.
Aside from both being able to take video and being easy enough to carry around, the products and the target markets don't intersect perfectly, so it's hard to predict one's success from the other.
This is certainly no predictor of absolute success, just an element of understanding the potential market.
