Can you give some examples of "Stripe camps out on the decoration side of things" ?
From what I've seen and used - Stripe also focuses big on usability and it appears also focuses heavily on developer experience.
What sites do you prefer that align more with the uber-functionalism lens?
I do find it sexy and bedazzling but that’s exactly why it is not interesting to me. Also Stripe’s taste is copied en-made to the point where it has become a self-propelling cliche in design. A good problem to have I suppose!
