Michael Giacchino's score for John Carter. It's sweeping, romantic, pulse-pounding, emotional - it's kind of perfect at what it's doing.
Christophe Beck's score for Ant-Man and The Wasp. One of the hosts of a film score podcast I listen to described it as "acrobatic", and I think that works. He mixes traditional orchestral stuff and electronica, and there's a lot of - I don't know the terminology here - beats that are off the beat? Anyway, I love it.
Jerry Goldsmith's score for Star Trek: The Motion Picture. As truly great as some of the ST film scores are, this one is the most beautiful.
Those are the three I can think of, and that I listen to the most often.
Honorable mentions, because I've been thinking a lot about them lately but haven't put them in rotation yet:
Shoji Yamashiro (aka Tsutomu Ohashi) score for Akira. Utterly unique, distinctive, uncanny, and unforgettable.
Jerry Goldsmith's score for the 1968 Planet of the Apes. Also highly unusual, inventive, off-kilter, and unsettling.
