I would argue that amazing UX _IS_ amazing marketing, precisely because people want to tell other people how awesome the UX is. I have a handy example: the meteoric launch of Clear.
Is this really true except for products that have a strong techie following? For me, I can't think of any product I recommended to someone mostly because of the amazing UX.
I'm not discounting the importance of UX, but it's easy to fall into the trap of focusing too much on the UX, and not on producing something people want, and finding a way to reach those people in a profitable, scalable way.
