Honestly? Depends on the fantasy and depends on the romance. Both can vary widely
Every fantasy is different. How much magic is there in your world? How does it work? How different are your magical races? How do the cultures clash up against each other or work together? Economics of kingdoms. Political structure. Even if you're going vanilla with elves, princesses and the like... there's so many ways you can break it down when you think about it long enough. And consequently, depending on the mechanics of your world and your author voice, you may vibe with one novel more than another. That's what I find, at least.
And the same goes with romance. There's so many different kinds of people. So many different kinds of ways for people to love each other and fall in love with one another. And it's a really personal thing to write about. Even if a love story is done really well, some people aren't going to gel with your perceptions of love itself. Which is inherently kind of scary.
It's been a minute since I read a love story that really hit me. But the ones that do usually rise pretty high in my esteem. And I respect every author's spin on fantasy if they do a spin on it I wasn't expecting.
TLDR; I can't choose.
