I don’t trust the yellow one for some reason. I feel like the mechanism wouldn’t work or may require more pressure than one would immediately give. The more mechanics involved, the more points of failure introduced.
I vouch for the basic ugly window smasher hammer.

I can say in my training experience the yellow one works great. It doesn’t require a wind up either.
Imo have a hammer in your glove compartment for helping OTHER cars. Have the small variety near each window so each occupant has a better chance of getting out (if the front right is crumpled, the glove compartment may not open)
That’s my move, but having anything is better than nothing
