I think this would just come down to taste. Or even timing - if you happen to read two fics with similar premises in a very short space of time, suddenly that storyline feels repetitive, whereas someone else might find it fresh and different from what they've been seeing.

I had a conversation with someone the other day who was talking about how all SW fic was already boring and relying too heavily on stupid recycled tropes. When I asked what they'd want to see that would be exciting and new, their answer was more coffee shop AUs, which I find to be one of the most overused tropes in all fandom. So different strokes for different folks.
